Searches for very rare decays of the Higgs boson by the ATLAS experiment

ATLAS event display showing a candidate event of the Higgs boson decaying into two muons

The Particle Physics Research Centre at QMUL have been searching for the very rare decay of the Higgs boson into two muons harvesting the data collected by the ATLAS experiment at CERN. Only one in every 5000 Higgs bosons decays in this specific way and the ATLAS team at QMUL lead by Antony Fray and Eram Rizvi have been studying this elusive decay in the last year. This study is crucial to establish the properties of the Higgs boson and how it interacts with the rest of the fundamental particles. The analysis has been now published by the prestigious journal series Physics Review Letters and it has been highlighted as Editor's Choice by the journal itself.
