Using atoms at temperatures colder than deep space, Rice University physicists have delivered overwhelming proof for a once-scoffed-at theory that's become a hotbed for research some 40 years after it first appeared. In a paper available online in Science Express, Rice's team offers experimental evidence for a universal quantum mechanism that allows trios of particles to appear and reappear at higher energy levels in an infinite progression. The triplets, often called trimers, form in special cases where pairs cannot. http://www.physorg.com/news179749630.html Physics Fri, 11 Dec 2009 10:27:59 EST news179749630 I can't imagine there is any more room for awards on the mantels at John Warnock's and Chuck Geschke's homes. The Adobe co-founders have been honored by trade groups, engineering societies, magazines and universities. But the awards just keep coming. http://www.physorg.com/news179651171.html Technology Thu, 10 Dec 2009 08:10:04 EST news179651171 (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 A recent experiment at the DOE's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structure. http://www.physorg.com/news177787801.html Physics Wed, 18 Nov 2009 17:31:37 EST news177787801 (PhysOrg.com) -- Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. http://www.physorg.com/news176567767.html Space & Earth Wed, 04 Nov 2009 14:37:05 EST news176567767 (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 Trapping and cooling a microscopic clump of gas and then suddenly releasing it would normally result in the gas rapidly expanding outward in all directions, like a spherical bubble. http://www.physorg.com/news168629014.html Physics Tue, 04 Aug 2009 18:25:10 EST news168629014 (PhysOrg.com) -- At a recent physics seminar at the Department of Energy`s Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton`s mass. http://www.physorg.com/news165491925.html Physics Mon, 29 Jun 2009 10:59:17 EST news165491925 (PhysOrg.com) -- The advantages of cloud computing were dramatically illustrated last week by researchers working on the STAR nuclear physics experiment at Brookhaven National Laboratory's Relativistic Heavy-Ion Collider. New simulation results were needed for presentation at the Quark Matter physics conference; but all the computational resources were either committed to other tasks or did not support the environment needed for STAR computations. Fortunately, working with technology developed by the Nimbus team at the U.S. Department of Energy's (DOE) Argonne National Laboratory, the STAR researchers were able to dynamically provision virtual clusters on commercial cloud computers and run the additional computations just in time. http://www.physorg.com/news157974755.html Technology Fri, 03 Apr 2009 10:55:03 EST news157974755 (PhysOrg.com) -- Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 Mega-electron volts. Physicists did not predict its existence because Y(4140) appears to flout nature's known rules for fitting quarks and antiquarks together. http://www.physorg.com/news156595642.html Physics Wed, 18 Mar 2009 11:48:17 EST news156595642 (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 (PhysOrg.com) -- Scientists of the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory have observed particle collisions that produce single top quarks. The discovery of the single top confirms important parameters of particle physics, including the total number of quarks, and has significance for the ongoing search for the Higgs particle at Fermilab's Tevatron, currently the world's most powerful operating particle accelerator. http://www.physorg.com/news155816209.html Physics Mon, 09 Mar 2009 11:17:28 EST news155816209 Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. http://www.physorg.com/news153928950.html Physics Sun, 15 Feb 2009 14:03:22 EST news153928950 (PhysOrg.com) -- A group of physicists studying heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC), a large particle accelerator located on Long Island, New York, recently showed that the collisions can create acoustic shock waves -- sonic booms. This new information could be used to learn even more about the intriguing state of matter produced during the collisions. http://www.physorg.com/news146486980.html Physics Fri, 21 Nov 2008 10:49:40 EST news146486980 (PhysOrg.com) -- New theory work at the U.S. Department of Energy`s Thomas Jefferson National Accelerator Facility has shown that more than half of the spin of the proton is the result of the movement of its building blocks: quarks. The result, published in the Sept. 5 issue of Physical Review Letters, agrees with recent experiments and supercomputer calculations. http://www.physorg.com/news140363908.html Physics Thu, 11 Sep 2008 14:58:28 EST news140363908
