Abstract

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton–proton collision data sets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb⁻¹ for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2±0.7 times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.
