In a paper published in Physical Review C, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN's Large Hadron Collider (LHC). https://phys.org/news/2025-05-alice-conversion-gold-large-hadron.html General Physics Thu, 08 May 2025 13:20:03 EDT news665928686 In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles such as electrons and protons, demonstrating the wave nature of propagating particles in quantum mechanics. https://phys.org/news/2024-08-alice-pattern-akin.html General Physics Mon, 12 Aug 2024 09:54:09 EDT news642675247 One way physicists seek clues to unravel the mysteries of the universe is by smashing matter together and inspecting the debris. But these types of destructive experiments, while incredibly informative, have limits. https://phys.org/news/2023-10-technique-near-miss-particle-physics-tau.html General Physics Wed, 18 Oct 2023 11:07:40 EDT news616846057 Quark–gluon plasma is an extremely hot and dense state of matter in which the elementary constituents—quarks and gluons—are not confined inside composite particles called hadrons, as they are in the protons and neutrons that make up the nuclei of atoms. Thought to have existed in the early universe, this special phase of matter can be recreated at the Large Hadron Collider (LHC) in collisions between lead nuclei. https://phys.org/news/2022-10-exploring-hidden-charm-quark-gluon-plasma.html Plasma Physics Thu, 20 Oct 2022 14:38:17 EDT news585495485 A new result from the ATLAS Collaboration at CERN studies the interactions of photons—particles of light—with lead nuclei at the Large Hadron Collider (LHC). Using new data collection techniques, physicists revealed an unexpected similarity to the experimental signatures of the quark–gluon plasma. https://phys.org/news/2021-07-particle-physicists-atlas.html Condensed Matter Tue, 13 Jul 2021 08:53:24 EDT news545385200 At the Large Hadron Collider (LHC) at CERN, the electromagnetic fields of Lorentz-contracted lead nuclei in heavy-ion collisions act as intense sources of high-energy photons, or particles of light. This environment allows particle physicists to study photon-induced scattering processes, which can not be studied elsewhere. https://phys.org/news/2019-11-atlas-probes-quark-gluon-plasma-photo-produced.html General Physics Wed, 27 Nov 2019 09:52:16 EST news494070733 The world's most powerful accelerator, the 27 km long Large Hadron Collider (LHC) operating at CERN in Geneva established collisions between lead nuclei, this morning, at the highest energies ever. The LHC has been colliding protons at record high energy since the summer, but now the time has now come to collide large nuclei (nuclei of lead, Pb, consist of 208 neutrons and protons). The experiments aim at understanding and studying the properties of strongly interacting systems at high densities and thus the state of matter of the Universe shortly after the Big Bang. https://phys.org/news/2015-11-cern-collides-heavy-nuclei-high.html General Physics Wed, 25 Nov 2015 11:04:53 EST news367671886 Researchers at the University of Kansas working with an international team at the Large Hadron Collider have produced quark-gluon plasma—a state of matter thought to have existed right at the birth of the universe—with fewer particles than previously thought possible. https://phys.org/news/2015-09-littlest-quark-gluon-plasma-revealed-physicists.html General Physics Thu, 03 Sep 2015 17:37:37 EDT news360520649 Three years ago, Rice physicists and their colleagues on the Large Hadron Collider's (LHC's) Compact Muon Solenoid (CMS) experiment stumbled on an unexpected phenomenon. Physicists smashed protons into lead nuclei at nearly the speed of light, which caused hundreds of particles to erupt from these collisions. But that wasn't the surprise. What was surprising is where these particles went: Rather than spreading out evenly in all directions, the particles coming out of the collisions preferentially lined up in a specific direction. https://phys.org/news/2015-07-physicists-liquid-like-particle-interactions-large.html General Physics Thu, 23 Jul 2015 06:50:01 EDT news356852831 In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions "melt" as a consequence of interacting with the hot nuclear matter created in these heavy-ion interactions. CMS has since updated and extended this result using additional data collected in the 2011 heavy-ion run, and the observation now has a significance of greater than 5σ (or 5 standard deviations), the gold standard for claiming a discovery in high-energy physics. https://phys.org/news/2012-12-cms-upsilon-particles-heavy-ion-collisions.html General Physics Thu, 20 Dec 2012 07:07:37 EST news275209634 (PhysOrg.com) -- In an experiment to collide lead nuclei together at CERN's Large Hadron Collider physicists from the ALICE detector team including researchers from the University of Birmingham have discovered that the very early Universe was not only very hot and dense but behaved like a hot liquid. https://phys.org/news/2010-11-early-universe-liquid-results-large.html General Physics Tue, 23 Nov 2010 14:34:29 EST news209745245
