Physicists from the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have observed a process called WWW production: the simultaneous creation of three massive W bosons in high-energy proton-proton collisions. Display of a candidate WWW→ 3 leptons + neutrinos event; the event is identified by its decay to a muon …

Physicists from the ATLAS (A Toroidal LHC ApparatuS) Collaboration at CERN’s Large Hadron Collider (LHC) have found first evidence of the Higgs boson decaying to a low-mass dilepton system (either an electron or a muon pair with opposite charge) and a photon. Known as Dalitz decay, this is one of …

Physicists from the ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact-Muon-Solenoid) collaborations at CERN’s Large Hadron Collider have reported strong evidence for the Higgs boson decay to a pair of muons. Candidate event displays of a Higgs boson decaying into two muons as recorded by CMS (left) and ATLAS (right). …

An international team of physicists, led by the University of the Witwatersrand (UW) in Johannesburg, South Africa, predicts the existence of a new particle that might aid in the understanding of dark matter. Proton-proton collisions events in which two high energy electrons and two high energy muons are observed. Image …
