Abstract
A study of anomalous couplings of the Higgs boson to vector bosons and fermions is presented. The data
were recorded by the CMS experiment at a center-of-mass energy of pp collisions at the LHC of 13 TeVand
correspond to an integrated luminosity of 138 fb−1. The study uses Higgs boson candidates produced
mainly in gluon fusion or electroweak vector boson fusion at the LHC that subsequently decay to a pair of τ
leptons. Matrix-element and machine-learning techniques were employed in a search for anomalous
interactions. The results are combined with those from the four-lepton and two-photon decay channels to
yield the most stringent constraints on anomalous Higgs boson couplings to date. The pure CP-odd
scenario of the Higgs boson coupling to gluons is excluded at 2.4 standard deviations. The results are
consistent with the standard model predictions.
