Search for lepton flavour violating decays of the higgs boson to μτ and eτ in proton-proton collisions at √s=13 TeV

A search for lepton flavour violating decays of the Higgs boson in the µτ and eτ decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 1...
