Abstract
A search for the Higgs boson decaying into a $Z$ boson and a photon with two electrons or muons and a photon in the final state is presented. A data set of 139 ${fb}^{−1}$ of $pp$ collisions at a center-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC is used. Estimates of Higgs boson signal and background contributions are performed based on the three-body invariant mass distribution. Corresponding systematic uncertainties are evaluated. Expected and observed limits on the signal strength, defined as ratio of observed and expected signal event yields, are shown.
