H (125) → ττ Channel

We have analyzed three of the six possible decay patterns of the τ lepton pairs in the H to &tau &tau decay channel. This decay mode is essential for establishing direct evidence of the τ coupling to leptons. Together with the non-observance of muonic decay mode, it gives also direct proof of the non-universality of the Higgs coupling, which is expected in the Standard Model. Once the latter is measured, it will allow a precise investigation of the mass dependence of the Higgs coupling. With the data of the upcoming Run-II of the LHC at 13 TeV, we will also investigate spin correlations within τ pairs as a further probe into the properties of the new boson.
