A century after physicist Ernest Rutherford published work proving the existence of the proton, much remains to be learnt about this ubiquitous particle
The CMS collaboration has searched for collision events in which the Higgs boson transforms into a photon and a hypothetical dark photon
The LHCb collaboration has observed a new pentaquark particle and has confirmed the pentaquark structure previously reported
