ttH production in final states with hadronically decaying tau leptons — •David Hohn, Andrea Sciandra, Markus Cristinziani, and Norbert Wermes — Physikalisches Institut, Universität Bonn

Evidence for the production of the Standard Model (SM) Higgs boson in association with a top-quark pair was found by ATLAS with 36.1 fb⁻¹ of 13 TeV pp collision data collected at the LHC in the years 2015–2016. This was achieved by analysing Higgs boson decays to bb and γγ, as well as leptonic final states which proceed via H→WW, H→ττ and H→ZZ. The latter Higgs decays are not distinguishable with the present sensitivity and are analysed jointly. The measured cross section of the ttH process is also a direct probing of the coupling between the Higgs boson and top-quark and is compatible with the SM prediction.

This talk will present the results of the analysis of final states that include hadronically decaying tau leptons. They are an important contribution to the precision of the total cross section measurement and sensitive to the Higgs–tau coupling.
