CP sensitive observable exploring tau lepton pairs from higgs at the LHC

Abstract

Copious production of tau leptons from the Higgs decay opens up possibility of determining the properties of the Higgs boson at the LHC in its leptonic decay channel. We construct several CP sensitive variables with principle hadronic decay of the tau which can be utilized for constraining the CP violating phase of Higgs to tau coupling. Asymmetries are constructed for these CP odd variables with 13 TeV LHC and 300 fb-1 of integrated luminosity.
