Higgs pair production in the MSSM with explicit CP violation

TL;DR

This paper investigates Higgs pair production in the MSSM with explicit CP violation, highlighting the impact of CP violation on Higgs boson interactions and the significance of radiative corrections.

Contribution

It provides a detailed analysis of Higgs pair production in the MSSM with explicit CP violation, emphasizing the role of radiative corrections and the mixing of Higgs states.

Findings

Both heavy Higgs bosons contribute due to CP violation.

Radiative corrections in the Higgs sector are significant.

Vertex radiative corrections remain small, similar to CP-conserving cases.

Abstract

In the minimal supersymmetric standard model with explicit CP violation, associated production of the lightest Higgs boson with heavier ones is analyzed. Due to explicit CP violation, the Higgs bosons are no longer CP eigenstates so that both of the heavy Higgs bosons contribute to the process. While the radiative corrections in the Higgs sector turn out to be quite important, the vertex radiative corrections remain small as in the CP conserving theory.
