Clocking nature’s heaviest elementary particle
The CMS collaboration has tested whether top quarks play by Einstein’s rules all day and all night

LHCb sheds light on two pieces of the matter–antimatter puzzle
The collaboration has found evidence of CP violation in decays of baryons and in decays of beauty hadrons into charmonium particles

A tale of two Higgs: CMS searches for the production of Higgs boson pairs
Using data from Run 2 of the LHC, the experiment has combined a comprehensive set of searches for di-Higgs production, a phenomenon that could provide physicists with clues to the stability of the Universe
