Approximate solutions for the Higgs masses and couplings in the NMSSM

Abstract

We find the approximate solutions for the Higgs masses and couplings in the NMSSM with exact and softly broken PQ--symmetry. The obtained solutions indicate that there exists a mass hierarchy in the Higgs spectrum which is caused by the stability of the physical vacuum.Comment: To appear in the proceedings of International Workshop on What Comes Beyond the Standard Model?, Bled, Slovenia, 19-30 Jul 200
