Description
The first experimental evidence is presented for the rare Higgs boson decay to a Z boson and a photon, with a statistical significance of 3.4 standard deviations. The result is derived from a joint interpretation of the searches performed by the ATLAS and CMS collaborations with their proton-proton collision data sets collected at the CERN LHC during 2015 and 2018. These correspond to integrated luminosities around 140 fb???1 for each experiment, at a centre-of-mass energy of 13 TeV. The observed signal yield is 2.2+-0.7 times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.
