Title: | Searches for lepton-flavour-violating decays of the Higgs boson in s=13 TeV pp collisions with the ATLAS detector | Authors: | Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2020 | Publisher: | Elsevier | Serial title, monograph or event: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 800 | Abstract: | This Letter presents direct searches for lepton flavour violation in Higgs boson decays, H→eτand H→μτ, performed with the ATLAS detector at the LHC. The searches are based on a data sample of proton–proton collisions at a centre-of-mass energy √s=13TeV, corresponding to an integrated luminosity of 36.1fb−1. No significant excess is observed above the expected background from Standard Model processes. The observed (median expected) 95% confidence-level upper limits on the lepton-flavour-violating branching ratios are 0.47%(0.34+0.13−0.10%) and 0.28%(0.37+0.14−0.10%) for H→eτand H→μτ, respectively. | URI: | https://hdl.handle.net/10316/106544 | DOI: | 10.1016/j.physletb.2019.135069 | Rights: | openAccess |
