Physicists at Queen Mary University of London (QMUL), together with international collaborators, have found evidence of the decay of Higgs bosons to muons. Muons are particles typically found in cosmic rays and have a low mass, and because of this the Standard Model of particle physics predicts that this decay ... [more]
