The Next Higgs Bosons in $E_{6}$ Inspired Supersymmetric Models with CP Violation

Abstract

We investigate the effect of CP violation in the Higgs sector of the U(1)′-extended MSSM. We are particularly interested in the mass and decay dependence of the second lightest neutral Higgs boson, in the presence of CP violating phases for μe f f . The masses of the neutral Higgs bosons are calculated at the one-loop level by taking into account the contributions from top and bottom (s)quark sectors. We study the production and decay channels of the second lightest neutral Higgs boson for a set of benchmark points consistent with the current experimental constraints. We then implement the model into standard packages and perform a detailed and systematic analysis of production and decay modes at the HE-LHC with 27 TeV.
