Abstract
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
→
μ
τ
)
<
0.15
(
0.15
)
%
and
B
(
H
→
e
τ
)
<
0.22
(
0.16
)
%
at 95% confidence level.
