Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are ...
The ATLAS experiment has confirmed that a trio of particles—a top-antitop quark pair and a W boson—occurs more frequently than expected in the wake of proton-proton collisions inside the Large Hadron Collider (LHC).

The ATLAS collaboration, the large research consortium involved in analyzing data collected by the ATLAS particle collider at CERN, recently observed the electroweak production of two Z bosons and two jets. This crucial observation, ...
When atomic nuclei such as gold or lead nuclei collide at high energy in particle colliders, they can produce quark–gluon plasma (QGP)—a hot and dense state of matter predicted to have existed shortly after the Big Bang. ...
