Higgs bosons of a supersymmetric $E_6$ model at the Large Hadron Collider

TL;DR

This paper explores the potential for CP violation in the Higgs sector of a supersymmetric $E_6$ model with extra gauge bosons, analyzing its phenomenology and possible Higgs production at the LHC.

Contribution

It demonstrates that explicit CP violation can occur at one-loop level in this model and studies the resulting Higgs phenomenology at the LHC.

Findings

CP symmetry may be explicitly broken at one-loop level.

At least one neutral Higgs could be produced via $WW$ fusion at the LHC.

The model's phenomenology is viable within a reasonable parameter space.

Abstract

It is found that CP symmetry may be explicitly broken in the Higgs sector of a supersymmetric $E_6$ model with two extra neutral gauge bosons at the one-loop level. The phenomenology of the model, the Higgs sector in particular, is studied for a reasonable parameter space of the model, in the presence of explicit CP violation at the one-loop level. At least one of the neutral Higgs bosons of the model might be produced via the $WW$ fusion process at the Large Hadron Collider.
