Search for lepton-flavor violating decays of the Higgs boson in the mu tau and e tau final states in proton-proton collisions at root s=13 TeV

Abstract: A search is presented for lepton-flavor violating decays of the Higgs boson to ?? and e?. The dataset corresponds to an integrated luminosity of 137 fb?1 collected at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. No significant excess has been found, and the results are interpreted in terms of upper limits on lepton-flavor violating branching fractions of the Higgs boson. The observed (expected) upper limits on the branching fractions are, respectively, BðH ? ??Þ < 0.15ð0.15Þ% and BðH ? e?Þ < 0.22ð0.16Þ% at 95% confidence level.
