TL;DR
This paper investigates how explicit CP violation in the MSSM Higgs sector influences the di-photon decay of the lightest Higgs, highlighting the enhancement of CP-violating effects via gluon fusion under specific parameters.
Contribution
It demonstrates the impact of CP violation on Higgs decay channels and production mechanisms within the MSSM, providing insights into observable effects in collider experiments.
Findings
CP violation significantly affects the di-photon decay of the lightest Higgs.
Gluon fusion enhances CP-violating effects for certain parameter choices.
The study identifies parameter regions with observable CP violation signatures.
Abstract
We study the effect of explicit CP violation in the Higgs sectors of the MSSM in the di-photon decay of the lightest CP-mixed Higgs state. Further it is shown that the gluon fusion production mechanism along with the di-photon decay enhances CP-violating effects for a large set of suitably chosen parameter values.
