  The minimal supersymmetric standard model (MSSM) is extended by including an
additional pair of constrained Higgs doublet superfields through which the
electroweak symmetry is nonlinearly realized. The superpotential couplings of
this constrained Higgs doublet pair to the MSSM Higgs doublet pair catalyze the
later nontrivial vacuum expectation values. The mass spectrum of the Higgs
scalars and Higgsino-gaugino sector is presented for several choices of
supersymmetry (SUSY) breaking and Higgs superpotential mass parameters. The
effect of the the additional constrained fields and multiple vacuum expectation
values on the lowest mass neutral Higgs scalar production and decay is
presented.
