Measurement of the Higgs Boson Couplings and CP Structure Using Tau Leptons at the LHC

Abstract

Results on the $H\to\tau\tau$ measurements performed by the ATLAS and CMS collaborations with the pp collision data collected at the LHC at $\sqrt{s}=$7 and 8 TeV are presented. These include a test of CP invariance in the VBF Higgs boson production. Experimental challenges for the test of the CP invariance in the $H\to\tau\tau$ decays are also reviewed.
