Study of the $H \rightarrow \tau \tau$ channel with ATLAS

After the discovery of the Higgs boson, the precision measurements of its properties and comparison with the Standard Model (SM) predictions became the crucial part of the LHC physics programme. A potential observation of deviations may lead to the discovery of a new physics beyond the Standard Model (BSM). The direct observation of the coupling of the Higgs boson to leptons and its measurements is of particular importance. In this contribution, the results of analyses of the Higgs boson properties in H->tau tau decay channel are presented. The measurements of Higgs boson boson signal strength in the tau tau final state are shown.
