Collisions between protons and lead ions at the Large Hadron Collider (LHC) have produced surprising behavior in some of the particles created by the collisions. The new observation suggests the collisions may have produced a new type of matter known as color-glass condensate. http://phys.org/news273220389.html Physics Tue, 27 Nov 2012 06:33:23 EST news273220389 (Phys.org)—At the LHC accelerator at CERN, collisions between protons and lead nuclei were established last week, for the first time in the ALICE detector. http://phys.org/news267089964.html Physics Mon, 17 Sep 2012 08:39:34 EST news267089964 (Phys.org) -- SLAC theorist Stan Brodsky and his collaborator Xing-Gang Wu of Chongqing University have just made the lives of high-energy particle theorists the world over a bit easier. They've demonstrated a way to literally take some of the guesswork out of predictions from quantum chromodynamics (QCD). QCD is the theory explaining the behavior of quarks, which in groups of three form protons and neutrons, and gluons, which carry the strong force that "glues" the quarks together. http://phys.org/news263536476.html Physics Tue, 07 Aug 2012 05:34:42 EST news263536476 Scientists working at the Institut Laue-Langevin, one of the world's leading centres for neutron science, have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered a new type of very short wave-length density wave. The team believe their discovery, published in Nature, will interest researchers looking at electronic systems, since high temperature superconductivity could result from this type of density fluctuations. http://phys.org/news252149896.html Physics Wed, 28 Mar 2012 13:00:01 EST news252149896 In its infancy, when the universe was a few millionths of a second old, the elemental constituents of matter moved freely in a hot, dense soup of quarks and gluons. As the universe expanded, this quark–gluon plasma quickly cooled, and protons and neutrons and other forms of normal matter "froze out": the quarks became bound together by the exchange of gluons, the carriers of the color force. http://phys.org/news228055479.html Physics Thu, 23 Jun 2011 14:00:22 EST news228055479 (PhysOrg.com) -- The three LHC-experiments (ALICE, ATLAS and CMS), which study lead-collisions have presented their latest results at the international Quark Matter 2011 conference, held in Annecy in France with over 750 participants from all over the world. The results are based on the analysis of new data from November-December 2010, when the LHC collided lead ions at approximately 14 times higher energy than was previously possible. http://phys.org/news225534734.html Physics Wed, 25 May 2011 09:40:21 EST news225534734 (PhysOrg.com) -- For a brief instant, it appears, scientists at Brook­haven National Laboratory on Long Island recently discovered a law of nature had been broken. http://phys.org/news188211977.html Physics Fri, 19 Mar 2010 10:06:51 EST news188211977 (PhysOrg.com) -- At a meeting this week of the American Physical Society in Washington, MIT Associate Professor of Physics Bernd Surrow reported on new results from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) that provide a better understanding of the internal structure of the proton, the basic building block of all nuclei. http://phys.org/news185652383.html Physics Wed, 17 Feb 2010 18:08:20 EST news185652383 Scientists at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. DOE's Brookhaven National Laboratory, report the first hints of profound symmetry transformations in the hot soup of quarks, antiquarks, and gluons produced in RHIC's most energetic collisions. In particular, the new results, reported in the journal Physical Review Letters, suggest that "bubbles" formed within this hot soup may internally disobey the so-called "mirror symmetry" that normally characterizes the interactions of quarks and gluons. http://phys.org/news185451423.html Physics Mon, 15 Feb 2010 10:18:51 EST news185451423 Recent analyses from the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference "atom smasher" at the U.S. DOE's Brookhaven National Laboratory, establish that collisions of gold ions traveling at nearly the speed of light have created matter at a temperature of about 4 trillion degrees Celsius — the hottest temperature ever reached in a laboratory, about 250,000 times hotter than the center of the Sun. This temperature, based upon measurements by the PHENIX collaboration at RHIC, is higher than the temperature needed to melt protons and neutrons into a plasma of quarks and gluons. Details of the findings will be published in Physical Review Letters. http://phys.org/news185451161.html Physics Mon, 15 Feb 2010 10:13:25 EST news185451161
