The one-loop correction to the neutral Higgs boson of the minimal supersymmetric standard model in explicit CP violation scenario

We investigate the neutral Higgs sector of the minimal supersymmetric standard model in explicit CP violation scenario. Within the context of the effective potential formalism, the masses of the neutral Higgs bosons at the one-loop level are calculated by taking into account the contributions of the following loops of ordinary particles and superpartners: top quark, the scalar top quarks, bottom quark, the scalar bottom quarks, tau lepton, the scalar tau leptons, W boson, the charged Higgs boson, the chargino, Z boson, the scalar and pseudoscalar Higgs bosons, and the neutralinos. We improve the one-loop radiative corrections to the neutral Higgs sector by explicitly including the contributions of the pseudoscalar Higgs boson loop to the masses of the neutral Higgs bosons at the one-loop level with explicit CP violation for a typical set of parameter values of the MSSM.
