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\pm0 …

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 for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.
