| Abstract: A search is presented for lepton-flavor violating decays of the Higgs boson to $\mu\tau$ and e$\tau$. The analysis is based on data corresponding to an integrated luminosity of 137 fb$^{-1}$, collected at the CMS detector of 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 and expected upper limits on the branching fractions are, respectively, $\mathcal{B}(\mathrm{H}\to\mu\tau) < $ 0.15% and $ < $ 0.15% and $\mathcal{B}(\mathrm{H}\to e\tau) < $ 0.22% and $ < $ 0.16% set at 95% confidence level. | ||
