Current measurements from ATLAS and CMS on Higgs CP properties.

Projected sensitivity improvements for HL-LHC in Higgs to ditau channel.

Potential of tau substructure analysis for CP measurements.

Abstract

This document is prepared for the LCWS2016 conference proceedings. It reviews the current results on the Higgs CP property measurements from both ATLAS and CMS experiments in the Higgs to diboson decays, and in the Vector Boson Fusion production of Higgs via the ditau decay channel. The projected sensitivity of the ditau signal in HL-LHC is briefly discussed. Finally, it gives the prospects for the CP measurement in the Higgs to ditau decay with the tau substructure developments at both collaborations.
