Neutral Higgs sector of the nexttominimal supersymmetric standard model with explicit CP violation
Abstract
The neutral Higgs sector of the nexttominimal supersymmetric standard model (NMSSM) with explicit CP violation is investigated at the 1loop level, using the effective potential method; not only the loops involving the third generation of quarks and scalar quarks, but also the loops involving the W boson, charged Higgs boson, and chargino are taken into account. It is found that for some parameter values of the NMSSM the contributions from the W boson, charged Higgs boson, and chargino loops may modify the masses of the neutral Higgs bosons and the mixings among them significantly, depending on the CP phase. In e^{+}e^{} collisions, the prospects for discovering neutral Higgs bosons are investigated within the context of the NMSSM with explicit CP violation when the dominant component of the lightest neutral Higgs boson is the Higgs singlet field of the NMSSM.
