Experiments offer tantalizing clues as to why matter prevails in the universe

August 16, 2010

A large collaboration of physicists working at the Fermilab Tevatron particle collider has discovered evidence of an explanation for the prevalence of matter over antimatter in the universe. They found that colliding protons in their experiment produced short-lived B meson particles that almost immediately broke down into debris that included slightly more matter than antimatter. The two types of matter annihilate each other, so most of the material coming from these sorts of decays would disappear, leaving an excess of regular matter behind.

This sort of matter/antimatter asymmetry accounts for the fact that just about all the material in the universe is made of the normal matter we're familiar with. The results are being published this week in papers appearing simultaneously in the APS journals and Physical Review D.

Physicists have long known about processes described by current theory that would produce tiny excesses of matter, but the amounts the theories predict are far smaller than necessary to create the we observe. The Tevatron experiments suggest that we are on the verge of accounting for the quantities of matter that exist today. But the truly exciting implication is that the experiment implies that there is new physics, beyond the widely accepted Standard Model, that must be at work. If that's the case, major scientific developments lie ahead.

The results emerge from a complicated and challenging analysis, and have yet to be confirmed by other experiments. If the matter/ imbalance holds up under the scrutiny of researchers at the in Europe and competing research groups at Fermilab, it will likely stand as one of the most significant milestones in high-energy physics, according to Roy Briere of Carnegie Mellon University in Pittsburgh. Briere summarizes the experimental results and their implications in a Viewpoint article in the current edition of APS Physics.

Ok. To take this statement at face value, I have to know what the "new physics" implies.

There isn't sufficient evidence that the universe isn't just background noise, so don't get too excited yet. Wait, did I say the universe? I meant the apparent results of the experiment in the article.

QCD cannot explain the discrepancy between matter and antimatter at all, Standard model includes CP violation through QCD Lagrangian and weak force, which explains only small portion of CP violation. You're not required in aether theory to explain it, concept of quantum foam is enough.
.Just because we can't detect any aether, doesn't mean there isn't any aether..
Massive scalar Higgs field doesn't differ from aether so much. Some theories consider, universe is formed with interior of black hole - again, this model is pretty close to dense aether model, because interior of black hole is always formed with dense matter. Etc...

..how the B-Meson broke down into more matter than anti-matter and how common that is with other particles?
The violation of matter-antimatter asymmetry would be the more pronounced, the higher or lower is the mass/energy density. B-mesons are heavy and massive particles, they're oscillating between flavors like neutrinos, for which such asymmetry was observed, too. It's evident, the physics of most massive particles is surprisingly similar to physics of these most lightweight ones.

In my theory the particles are nothing else, then more dense clusters of vacuum foam, which gets more dense after introduction of energy in similar way, like soap foam during shaking. Every foam is formed with bubbles separated with membranes with at least two surfaces, along which the energy waves are spreading. I'm assuming, the particles are formed with waves, which are spreading along internal sides of foam membranes, whereas the particles of antimatter are formed with vibrations of outer sides.

In sparse foam the membranes separating bubbles are thin and their surface gradients doesn't differ with curvature of space-time very much. In thick foam full of energy the situation is different, though. Vacuum foam is forming small round bubbles from perspective of human observer, and the difference between stability of matter and antimatter becomes apparent there.

This behavior makes cosmological explanation of matter abundance somewhat tricky, because the current generation of particles and antiparticles doesn't differ very much in their properties. The theories based on properties of common particles therefore cannot explain the abundance of antimatter so easily. For relevant explanation we should consider hot & dense state of Universe briefly after Big bang, when properties between matter and antimatter differed significantly.

Actually yes - it's manifestation of anthropic principle and/or "simillia simillibus observantur" principle. The object formed with bubbles of negative curvature will interact with another bubbles preferably. In this way the antiparticle bubbles will be dispersed with fluctuations of vacuum, which are of slightly negative curvature, too.

But it still doesn't explain, why just two forms of matter exist here, and why they differ in their properties in so complex way. Foam model provides some testable predictions, too - for example it explains cumulation of dark matter around black holes and inside of streaks of dark matter.

For me is somewhat surprising, why people who are talking about fabric of space and/or quantum foam never used this concept in its intrinsic, geometric way.

We can met with the CPT asymmetry even in human society at many places. For example, capitalism and communism are two dual socio-economical structures, analogous to matter and antimatter. But because capitalism concentrates capital, wheres communism tends to disperse it and you cannot base human society on dispersion of capital from long perspective, inside of stable society the capitalism always wins the competition. We can follow it by date of day of tax freedom, which defines well the ratio of socialism and capitalism inside of particular country.

As another example can serve the Closed/Open source SW ratio on the free market and/or sex ratio in growing society. Because females are more social and they're actually doing children, they're slightly more frequent at the end of their life, too.

We know, photon pairs are forming particle-antiparticle pairs inside of strong electromagnetic field. The strong gravity field has the opposite effect (up to certain level) and it dissolves the particle-antiparticle pairs into radiation. When photons are escaping from gravity field, they tend to condense into particles, which can be observed in black hole jets. But because the gravity field of black hole is of strong positive curvature, the particles of matter are attracted more to black hole, then the particles of antimatter (which are of slightly negative curvature) and they form a condensate cloud around it, i.e. galaxy. Whereas the antiparticle are forming the outer surface of galaxy, i.e. galactic halo. I presume, most of "missing antimatter" is actually hiding there.

Because matter and antimatter react mutually under formation of large amount of energy (i.e. annihilation), we can compare the matter-antimatter mixture escaping the black hole to the mixture of of carbon particles and oxygen inside of candle flame. If this flame is cooled slowly, then the carbon has enough of time to react with oxygen quantitatively.

But if we cool flame fast, it will start to decompose back under formation of black soot - which condenses, whereas the oxygen escapes. In this way, I'm assuming, the observable matter was formed during fast cooling of quasars, which lead to condensation and separation of matter and antimatter. In analogous way, we can observe traces of antimatter around massive stars and or black holes, where fast cooling or radiation occurs. Actually the behavior of matter-antimatter equilibrium doesn't differ from chemical equilibrium and Le-Chatelier's principle, which is driving classical thermodynamics.

They concentrating both, but antiparticles are preferred. Because antiparticles are formed mostly by positrons, some portion of protons and heavily ionized atom nuclei can survive inside of dark matter too. Their repulsive EM forces are in equilibrium with their gravity.

If black holes would be formed with singularities, then the highest curvature of space-time would exist just at the center of black holes. But we know, at the case of real massive bodies the space-time is actually flat just at the center. Therefore the gravity field around black holes (and large galactic clusters, too) has a bell shape profile with area of positive curvature at center. Whereas the outer zone is of slightly negative curvature and it exhibits a weak repulsive force, responsible for dark energy. Because of its negative curvature, it attracts and collects negatively curved particles of antimatter preferably. Does it all appear logical?

Question, I don't understand the reply to your question, so I'll try.

The experiment is to collide protons with anti-protons. The experiment wasn't being "conducted" soley with matter. I believe the more appropriate question is whether the background noise found in the matter rich environment (unfortunate condition of being in our universe) isn't clouding the findings. The next step is to reproduce the findings and ensure that they are in fact the result of the CP violation and not some other phenomenon leaking in.

Vacuum bubbles aside, the question is, "Why this universe?" Scientists want an answer for why there is an abundance of matter in this universe. The current method is isolate the bias, then search for a root cause. The Standard Model hasn't been able to predict the bias in a verifiable way.

Yet.

Vacuum bubbles aside, the question is, "Why this universe?"
From sufficiently distant/high dimensional perspective all objects can be approximated by pin-point particles. The random density fluctuations are of hyperbolic unparticle geometry, like the density fluctuations inside of dense condensing gas (supercritical fluid in particular). If you don't like aether concept, you can think about space-time curvatures and/or gravitons, which exhibit weak properties of both matter (with positive curvature), both energy (with negative curvature). They're forming both smallest, both largest structures of observable reality observable. If we could slow-down time many bilion-times, we would see vacuum full of subtle fluctuations (microwave photons), similar to transparent hot air above camp fire.

Actually we can visualize them in certain extent for observation with naked eye, if we watch the surface of superfluid helium at few Kelvins temperature above zero. They're actually quite large.

Electron and positron never touches mutually during their mutual annihilation. Actually I do believe, matter and antimatter would annihilate mutually via subtle gravitational waves at distance. Which brings the question: can we detect the antimatter character of some unknown matter without actually annihilating some? It's similar to observation of ice - you cannot actually detect its coolness without some heating of its surface and accelerating its melting in such way.

We can believe, the decomposition of B-mesons (a composite particles of quark and anti-quark) would be exactly balanced in completely empty universe. But because we're observing it, we're exchanging some subtle energy with it via gravitational waves, which are dissolving/annihilating the antimatter preferably. And because B-mesons interact at short distance only, this lost is significant.

Some predictions could be tested during few years. For example we can ask, whether at some distant areas of Universe the antimatter galaxies cannot exist? Such galaxies could be detected at distance. For example, the galaxies which are not from our material universe are supposed to fail in creation of shadows on the CMB radiation, thus forming parallel universes effectively. Recent astronomical research did show us, that several galaxy clusters really do not produce a shadow at CMB radiation. http://arxiv.org/.../0510160

Even more fantastic would be detection of more antimatter types, which would annihilate mutually. We can expect, at remote areas of Universe the matter/antimatter symmetry will be broken in such a way, the matter of one galaxy would annihilate with matter of another galaxy at least partially. If such pieces would survive the travel through cosmic space required for their mutual contact, we could use them as a source of energy.

Question, to address the first part of your statement. From the "source" article at physics.aps.org:
This means that they see pairs of positive muons, among the debris of their proton-antiproton collisions more often than they see pairs of negative muons.

To Pyle: Quantum physics is about the particles that are smaller than the atom. You need an atom smasher for that. It is known that when you smash an atom you get a bit more matter than antimatter. What is not known is the reason. The team is saying they think it is because the meson phenomenon is one of the most frequent occurences on the quantum scale (world), but not all occurences are known. To break it down, say after you smash the atom you get 100 matter and 98 antimatter (slighly more matter), the result is 2 matter since antimatter destroys matter. Have this phenonmenon occuring in quasi infinite numbers and that explains why our universe is made up of atoms and corresponding elements instead of antimatter. Conversily, if what was happening was 98 matter, 100 antimatter, output 2 antimatter, repeated quasi infinite = antimatter universe (no elements). You have to remember that the atom is allowed exist only because of the laws in the quantum world permit it to.

eric96,
I agree with most of your points, but will make a subtle distinction.

My understanding is that the bias towards matter (CP violation) in previously observed reactions/measurements did not explain the universe (big bang yada yada). The more recent results mentioned in this article, show a more biased reaction that could help better explain the matter rich universe we exist in. However, the finding is preliminary and outside causes of the matter rich results haven't been scientifically ruled out yet.

All observations are merely a gamble. When one observes the universe the only resultant description will have to require the presences of the measuring devices used to formulate that description. There are no absolutes outside of measurement as existence doesn't exist without an observer.

Hi Question. Not all articles on Physorg are created equal. Try http://physics.ap...es/v3/69 for additional info. It clearly shows that collisons
took place between protons and anti-protons (and not between positrons and electrons as Jigga/Xaero and company mentions). Also note that even in cases where you collide only matter, it can convert to high energy photons that then decay into matter/antimatter particle pairs, so that's not too much of a problem. In any case, the researchers were looking at the decay products of the B-mesons produced in the collisions and noting an imbalance in those decay products. It doesn't really matter how you get the B-mesons in the 1st place. BTW, those chambers hold a pretty hard vaccuum.

How can you just look at the decay of the B-meson?

Furthermore are B-mesons really a fundamental particle or a composite of several different more fundamental particles, quarks?

Well, computers *are* used to account for all detected decay products and filter out the vast majority of collision results as these are rather mundane in the vast majority of cases. That's why they need so much data.

Furthermore are B-mesons really a fundamental particle or a composite of several different more fundamental particles, quarks?


This is pretty easy to look up, Question, but no, B-mesons aren't fundamental. They are a composit of a bottom anti-quark and another, positively charged quark (except for the Top as its lifetime is too short, and the Bottom, which makes another beast). So they are made up of both matter and antimatter to begin with, and some B-mesons oscillate into there own anti-particles billions of times before decaying.

Well, there is always about a 100% chance that answers for unknowns are to be found in areas where you are not looking and don't understand.

Meaning..we need to stop pressing the old buttons of 'familiarity', and that by now:...we should psychologically do our best to understand do not work -and move on to unknowns. For if the attempts at connective tissue to bridge the gap with today's theory fail to reach the 'new', then it should not be surprising to us that those attempts are 'incorrect'.

One look at the 'surprising' research and 'surprising and unexpected' results that happen every day, now, it seems, in baseline physics (4% different mass on proton, for example) well.. these things (discoveries) illustrate this point ~quite clearly~.

It boils down to conservation laws. Particle decay modes are not purely, completely random. In other words, it's not magic. These decay modes are governed by probability and all original properties (mass/energy, momentum, spin, charge, etc.) must be conserved one way or another in the decay products. So you start just 4 possibilities and have a fixed set (if large) of possible decay product combinations. So you *can* work your way back to the original particle. If you really want to get into it:

All this discussion of the complexity and seemingly enormous variety of combinations of "fundamental" particles [or should that be "vibrations"?] is quite confusing. Simple minded me though wonders if the basic asymmetry underlying matter versus anti-matter is not smallwards versus bigwards. I understand the basic concepts of fractals and self-symmetry and power law relationships - well the really basic concepts anyway - but I see that in nature things can be similar at different orders of magnitude but not identical.

This is different from mathematical representations of fractals where, in principal anyway, there is always a potentially infinite supply of numbers at whatever scale you may choose. In nature, "as above so below" is never completely true. The separation at the start of our current universe - the inflation - was an elaboration of bigwards versus smallwards. This quasi dimension permeates space-time.

The CMB we've recorded most likely was Gamma, however, that doesn't mean we've recorded everything within the CMB. The LISA survey is looking for gravity waves originating from the CMB and prior.

Indeed... In dense aether theory gravitational waves are superluminal and they spread through vacuum like sound waves at the water surface, i.e. like tiny noise, known as a cosmic microwave background. It means, no gravitational waves (in sense of harmonic perturbations of space-time) are really observable, only less or more periodic changes of intensity of CMB noise. And this is what was observed with GEO 600 observatory recently and interpreted with holographic model of Universe, too.

http://prd.aps.or.../e124009

In holographic theory the observable Universe is formed like projection of gravitational waves from surface of black hole, where we are living in. Such projection must be inherently superluminal, or it couldn't work at all.

So, perhaps gravity itself is the resultant of the matter/antimatter annihilation -in other words, could gravity BE the Energy of Annihilation?

Or, alternatively, perhaps the Energy of Annihilation is the Vacuum Energy, and since it is many orders of magnitude greater than matter, this explains why vacuum energy continually inflates space? This would also imply that expansion would cease, at some point.

The Universe is expanding but not into space. Rather space itself is expanding. This stretches out the light that was released at the end of the Dark Era when light decoupled from matter. That is when the temperature of matter got low enough for the free protons to capture the free electrons and form atomic hydrogen. Before that light could only go very short distances before being absorbed by an electron.

Thus the initial temperature of the light of the CMB was NOT at the level of gamma rays. Matter was simply not that hot anymore. It was below the temperature of the Sun. For anyone that disagrees just take a look at the Sun. It is opaque for the same reason the early Universe was.

Since then the light released has cooled as it is stretched.

My own thought on this is that if light is pulled out to a longer wavelength by the expansion of space doesn't that mean that the light had to push space.

This is just a speculation of yours, not supported with any source. For example here you can read clearly:

"Cosmic background photons have their origin at the matter/anti-matter annihilation era and, thus, were formed as gamma-rays."

During inflation the space-time expanded in 10E+40 :1 ratio. Only photons of gamma rays could obtain the final wavelength of CMB, i.e. 2 cm under such circumstances - it's trivial arithmetic.

Primordial Era

The Primordial Era is defined as "-50 < n < 5". In this era, the Big Bang, the subsequent inflation, and Big Bang nucleosynthesis are thought to have taken place. Toward the end of this age, the recombination of electrons with nuclei made the universe transparent for the first time.


http://en.wikiped...Big_Bang

After about 379,000 years the electrons and nuclei combined into atoms (mostly hydrogen); hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is known as the cosmic microwave background radiation.

Two American scientists, George Gamow and Robert Dicke independently predicted that very high temperatures must have existed at the time of the Big Bang. If so, the Universe would then have been filled with very high energy photons, initially in the form of gamma rays. As the Universe has expanded the radiation has become less energetic and would now be in the far infra red and very short wave radio parts of the spectrum. But this means that if one could place a thermometer in the space between the galaxies it would not read absolute zero but a value of a few degrees above absolute zero. This radiation is now normally called the Cosmic Microwave Background radiation (CMB) but has had alternate names such as the Relict Radiation.

I don't care what crap you post or what great sources you post that are about the time BEFORE the Universe became transparent because NONE of that matters. We can only see back to the beginning of transparency. This is inherent in the way light interacts with ions.

Just because I posted it doesn't make it wrong. I wasn't even talking to you as you are a waste of time. I am only posting now to clear up the erroneous statements you made about my posts.

Aug 19, 2010, that CMB started off as gamma rays
Because it didn't. It started out as UV on down. When the energy levels were still high enough to produce gamma radiation the light was getting absorbed almost as soon as it emited. It was the FINAL light emited by matter as light and matter decoupled that produced the CMB. This is true whether inflation was real or not. Whether the Universe bounces or not.

Since the evidence shows the Universe expanding as far as we can see we can make a reasonable that it was expanding in the time before we can see. As we project back in time the matter is more compressed the energy is more concetrated. But we can only project the light back to the period when the Universe was opaque. Before that all light was being absorbed and reemited. Its a pretty straight forward idea once you accept the evidence of expansion.

The CMB can't tell us a lot about the time before transparency except by analyzing the variation in temperature.

No, but they do give us ways to look at things. There could have been space already in either of those. Pretty much has to be there in the Brane Cyclic idea. Until the evidence for acceleration was found most Cosmologists seem to have preferred the idea of a JUST barely closed Universe. A closed Universe pretty much had to have created the space as it expanded. There is more flexibility in the way things could have been in an open Universe.
I love it when people say the universe can from nothingness or that time and space began with the Big Bang
It fit the evidence that was leading to the idea of a closed Universe. Something I was never comfortable with due to the major hand waving that was going on to claim the Universe was closed. However at the moment there is nothing that we can say about time before the Big Bang that is more than speculation.

The Big Bang theory doesn't say that 'everything' (galaxies) are 'expanding out at c'. The galaxies don't really have a large relative velocity (whatever the distance) - they can be considered to be more or less stationary. They only appear to be receding at near c at large redshifts because there is so much intervening space which is being created ('expanded').

At this temperature (4000 K) the universe is cold enough for atoms to exist. So, quickly electrons combine with atom nuclei to form atoms. This process is called recombination.

Before recombination, while the gas was ionized, free electrons collided with the CMB photons quite often. This kind of collisions is called scattering. Then suddenly, when all free electrons jumped into atoms, CMB photons had nothing to collide with. They just flew in straight lines after that.

Thus, when we see a CMB photon coming straight into our ``eyes'', we see it coming from the moment of last collision with the free electron. This moment and place in the universe is called the surface of last scattering.
Which again agrees with me about what we actually are measuring in the CMB. The light from the time the Universe became transparent.

So thank you for that.

As the universe expanded and cooled there finally came a time, ~380,000 years after the origin, when the typical photon energy became low enough to allow atoms to form. There were then no free electrons left to scatter radiation so the universe became transparent. This is thus as far back in time as we are able to see. At this time the universe had a temperature of ~3000K
