Dying, for stars, has just gotten more complicated. For some stellar objects, the final phase before or instead of collapsing into a black hole may be what a group of physicists is calling an electroweak star. http://www.physorg.com/news180021867.html Physics Mon, 14 Dec 2009 14:05:03 EST news180021867 (PhysOrg.com) -- New high-energy particle research by a team working with data from Fermi National Accelerator Laboratory further heightens the uncertainty about the exact nature of a key theoretical component of modern physics -- the massive fundamental particle called the Higgs boson. http://www.physorg.com/news179421292.html Physics Mon, 07 Dec 2009 15:15:45 EST news179421292 (PhysOrg.com) -- Troubles at the Large Hadron Collider have led some physicists to suggest the Higgs boson is sabotaging its own discovery. Nahn explains why he disagrees. http://www.physorg.com/news175181725.html Physics Mon, 19 Oct 2009 14:36:42 EST news175181725 (PhysOrg.com) -- Quarks, the most fundamental constituents of matters, are classified into six species grouped into three generations as predicted by Professors Kobayashi and Maskawa. The purpose of the B factory experiment is to elucidate the fundamental laws of elementary particles by producing B mesons that contain the second heaviest quark (bottom). An international team of researchers at the High Energy Accelerator Research organization (KEK) in Tsukuba, Japan, the "Belle collaboration", has achieved many successes, including the discovery of CP violation in B meson decays and proof of the Kobayashi-Maskawa theory, the discoveries of new decay processes in B decays and D-meson mixing as well as the observation of new resonances. http://www.physorg.com/news171567213.html Physics Mon, 07 Sep 2009 18:40:45 EST news171567213 A tiny fraction of a second following the big bang, the universe allegedly experienced the most inflationary period it has ever known. http://www.physorg.com/news161612749.html Physics Fri, 15 May 2009 13:26:22 EST news161612749 The Large Hadron Collider is an enormous particle accelerator whose 17-mile tunnel straddles the borders of France and Switzerland. A group of physicists at the University of Nevada, Reno has analyzed data from the accelerator that could ultimately prove or disprove the possibility of a fifth force of nature. http://www.physorg.com/news160128782.html Physics Tue, 28 Apr 2009 09:13:26 EST news160128782 (PhysOrg.com) -- "In many ways, the standard model of cosmology works very well," Jose Cembranos tells PhysOrg. "However, there are very basic features that we just do not know. We have dark energy and dark matter. They dictate the evolution of late time cosmology. They both together constitute more than 95 percent of the energy content of the present Universe." If this is the case, why do we trust the standard model? It can`t explain such a large portion of the universe. http://www.physorg.com/news159444907.html Physics Mon, 20 Apr 2009 11:17:07 EST news159444907 (PhysOrg.com) -- The territory where the Higgs boson may be found continues to shrink. The latest analysis of data from the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab now excludes a significant fraction of the allowed Higgs mass range established by earlier measurements. Those experiments predict that the Higgs particle should have a mass between 114 and 185 GeV/c2. Now the CDF and DZero results carve out a section in the middle of this range and establish that it cannot have a mass in between 160 and 170 GeV/c2. http://www.physorg.com/news156160849.html Physics Fri, 13 Mar 2009 11:01:43 EST news156160849 (PhysOrg.com) -- Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory have achieved the world's most precise measurement of the mass of the W boson by a single experiment. Combined with other measurements, the reduced uncertainty of the W boson mass will lead to stricter bounds on the mass of the elusive Higgs boson. http://www.physorg.com/news156002472.html Physics Wed, 11 Mar 2009 15:02:14 EST news156002472 Physicists at Indiana University have developed a promising new way to identify a possible abnormality in a fundamental building block of Einstein's theory of relativity known as "Lorentz invariance." If confirmed, the abnormality would disprove the basic tenet that the laws of physics remain the same for any two objects traveling at a constant speed or rotated relative to one another. http://www.physorg.com/news150388964.html Physics Mon, 05 Jan 2009 14:42:44 EST news150388964 (PhysOrg.com) -- `It's pretty clear that the standard model of physics is not enough to explain all the phenomena in nature,` Tomasz Skwarnicki tells PhysOrg.com. `Through looking at a variety of phenomena - one of them being dark matter - we know that there is a whole set of interactions beyond our standard model.` Skwarnicki`s work doesn`t deal with dark matter, but the Syracuse University physicist has been working on models of physics that go beyond the standard. http://www.physorg.com/news143714451.html Physics Mon, 20 Oct 2008 09:40:51 EST news143714451 After 20 years of construction, a machine that could either verify or nullify the prevailing theory of particle physics is about to begin its mission. CERN's epic Large Hadron Collider (LHC) project currently involves 25 University of Michigan physicists and students. More than 100 U-M researchers have been involved in the project over the years. CERN is the European Organization for Nuclear Research, located in Geneva, Switzerland. http://www.physorg.com/news139827808.html Physics Fri, 05 Sep 2008 10:03:28 EST news139827808 (PhysOrg.com) -- Later this year, the world's largest and most powerful particle accelerator, the Large Hadron Collider near Geneva, Switzerland, will begin operating, sending beams of protons hurling around circular tracks in opposite directions at nearly light-speed and then forcing them to collide, producing a spray of energy and matter. http://www.physorg.com/news135938428.html Physics Tue, 22 Jul 2008 09:40:28 EST news135938428
