Coexistence of CP eigenstates in Higgs boson decay

TL;DR

This paper discusses how CP violation in supersymmetric models can lead to the simultaneous observation of CP-even and CP-odd states in Higgs boson decays to two photons, providing potential experimental signatures.

Contribution

It introduces the possibility of observing coexistence of CP eigenstates in Higgs decay due to supersymmetric CP violation effects.

Findings

Evidence for both CP-even and CP-odd states in Higgs decay to two photons.

Supersymmetric CP violation can produce observable effects in Higgs decay channels.

Potential experimental signatures for CP violation in Higgs processes.

Abstract

The supersymmetric extension of the standard model contains an intrinsic sourceof CP violation mediated by the charginos. As an effect, both CP-even and CP-odd final states could be observed in the Higgs boson decay into two photons whose evidences were reported recently.
