The astonishing result, achieved by the CMS (Compact Muon Solenoid) collaboration, represents the first-ever observation of single top quark production with W and Z bosons, a process known as tWZ ...

Amid the chaotic chains of events that ensue when protons smash together at the Large Hadron Collider in Europe, one particle has popped up that appears to go to pieces in a peculiar way. All eyes are ...

A new theory-based approach provides access to the minute transverse motion of quarks within protons. Nuclear physicists have developed a new theoretical framework that allows them to calculate a ...

Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

New high-energy particle research by a team working with data from Fermi National Accelerator Laboratory heightens uncertainty about the exact nature of a key theoretical component of modern physics - ...

Quark coalescer: the LHCb experiment being upgraded several years ago. (Courtesy: Maximilien Brice/CERN) Physicists working on the LHCb experiment have seen evidence that “quark coalescence” plays a ...

Physicists see top quarks and Higgs bosons emanating from the same collisions in new results from the Large Hadron Collider. Today two experiments at the Large Hadron Collider at CERN announced a ...

The standard model of particle physics has been a spectacularly successful theory for explaining the properties and interactions of fundamental particles, with many measurements confirming its ...

Researchers at the CERN Large Hadron Collider have discovered a doubly charming new particle, which has long been theorized to exist. Named Ξ cc ++ (Xi cc ++) (and no, we don't know how to pronounce ...

In the quest to advance our knowledge of the Universe, the biggest advances always seem to come when an experiment or measurement indicates something new: something our best theories to that date hadn ...

The experiments at the Large Hadron Collider (LHC) detect rare events on a daily basis, but some are exceptionally rare, such as this latest result from the CMS collaboration. For the first time, the ...
