Experiment brings precision to a cornerstone of particle physics

In a paper published yesterday in the journal Physical Review Letters, the COMPASS experiment at CERN reports a key measurement on the strong interaction. The strong interaction binds quarks into protons and neutrons, and ...

Experiment confirms existence of odd particle

Scientists working on the CMS experiment at the Large Hadron Collider have confirmed the existence of an odd, puzzling particle first observed a few years ago at DOE's Tevatron particle collider. Members of the CMS collaboration ...

Supercomputing the difference between matter and antimatter

(PhysOrg.com) -- An international collaboration of scientists has reported a landmark calculation of the decay process of a kaon into two pions, using breakthrough techniques on some of the world's fastest supercomputers. ...
