Content
Existing studies of Higgs-tau Yukawa coupling allows for the presence of a non-zero CP-odd contribution. This is usually probed and constrained at the LHC by studying the distribution of events with respect to the angle between the two tau decay planes in H -> tau+ tau- decay. We study another interesting signature of CP violation, namely forward-backward asymmetry in the decay H -> tau+ tau- gamma. This CP-asymmetry interestingly requires interference of tree and one-loop level contributions. We focus on how this asymmetry can be quantified and whether such a study would be feasible in the high luminosity phase of LHC.
