S.W. Ham, S.G. Jo, S.K. OH, and D. Son

TL;DR
This paper investigates the effects of explicit CP violation on the neutral Higgs sector in the MSSM, analyzing production processes at the LHC and ILC and how they depend on the CP phase, with implications for Higgs detection.
Contribution
It provides a detailed one-loop level analysis of neutral Higgs production cross sections in the MSSM with explicit CP violation, highlighting the CP phase dependence.
Findings
Higgs production cross sections vary by 3% to 19% with CP phase changes.
The study covers both LHC and ILC relevant processes.
CP violation effects can significantly influence Higgs detection prospects.
Abstract
We study the neutral Higgs sector of the minimal supersymmetric standard model (MSSM) with explicit CP violation at the one-loop level. We take into account the one-loop contributions by the top quark, the stop quarks, the bottom quark, the sbottom quarks, the tau lepton, the stau leptons, the boson, the charged Higgs boson, the charginos, the boson, the neutral Higgs bosons, and the neutralinos. The production cross sections of the neutral Higgs boson are calculated to the leading order. The processes in our consideration are divided in two groups: the Higgs-strahlung and gluon fusion processes accessible at the CERN Large Hadron Collider (LHC), and the vector boson fusion and Higgs-strahlung processes accessible at the International Linear Collider (ILC). In particular, we investigate the dependence of these processes on the CP phase arising from the U(1) factor of…
