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, B(H -> mu t) < 0.15(0.15)% and B(H -> e tau) < 0.22(0.16)% at 95% confidence level.eninfo:eu-repo/semantics/openAccessNONCONSERVATIONSearch 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 TevArticle10.1103/PhysRevD.104.0320132-s2.0-85114624026
