CERN: Damage to new collider forces 2-month haltALEXANDER G. HIGGINS
“Up” and “down” quarks make up protons and neutrons in the nuclei of atoms, and the others can be created by high-energy processes like smashing things at high speed in theLarge Hadron Colliderat CERN. Some particles, calledmesons, can also be created by combining quarks and anti-quark...
The LHCb collaboration at CERN today submitted a paper toPhysical Review Letterson the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s. It is only the fourth subatomic particle known to exhibit such behavior. Matter and antimatter are thought to ha...
This fundamental particle, whose existence was predicted as a consequence of theories developed in the mid-1960s1,2, was discovered by teams working on the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN, the European particle-physics laboratory near Geneva in Switzerland. ...
AtCERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. The Large Hadron Collider (LHC), which began working in 2008, is the world’s largest and most powerfulparticle accelerator; it is housed in an underground tunnel...
the ridge has also been seen in high-multiplicity proton collisions at the Large Hadron Collider, giving the first indication that proton collisions could present heavy-nuclei-like properties. Studying these processes more precisely will be key to better understand the microscopic mechanisms of thequark...
at the 90 percent probability level. Earlier experiments at the Large Electron-Positron Collider at CERN excluded a Higgs boson with a mass of less than 114 GeV/c² at 95 percent probability. Calculations of quantum effects involving the Higgs boson require its mass to be less than 185 GeV...
The Large Hadron Collider (LHC) at CERN has allowed the ATLAS and CMS experiments to collect a large amount of proton-proton collision data at 7 TeV and 8 TeV centre-of-mass energies. This dataset was used to discover a Higgs boson with Standard Model-like properties at a mass of about...
Scientists at CERN's Large Hadron Collider may have created the world's hottest man-made temperature, forming a quark-gluon plasma that could have reached temperatures of 5.5 trillion degrees Celsius or 9.9 trillion Fahrenheit. By Adi Robertson,a senior tech and policy editor focused on VR, onli...
What if you could test a new theory against data from the Large Hadron Collider (LHC)? Better yet, what if the expert knowledge needed to do this was captured in a convenient format? This tall order is now on its way from the ATLAS Collaboration at CERN, with the first open release of...
