Abstract: (APS)

A search is presented for lepton-flavor violating decays of the Higgs boson to

μ τ

and

e τ

. 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 \to μ τ) < 0.15 (0.15) %

and

B (H \to e τ) < 0.22 (0.16) %

at 95% confidence level.
