Approximate solutions for the Higgs masses and couplings in the NMSSM
arXiv:hep-ph/0411275
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.
