Implications of vacuum stability constraints on the nonminimal supersymmetric standard model with lepton number violation
Abstract : We carry out a detailed analysis of the scalar sector of the nonminimal supersymmetric standard
model with lepton number violation, and study the constraints imposed on it by the stability of the
electroweak symmetry breaking vacuum. The model contains a trilinear lepton mumber violating
term in the superpotential together with the associated supersymmetry breaking interactions
which can give rise to neutrino masses. We evaluate the mass matrices for the various boson and
fermion modes and then discuss the effect that the lepton number violating interactions have on
the mass spectra using a phenomenological precription to implement the experimental constraints
on the light neutrinos mass matrix. We also discuss qualitatively the conditions on the lepton
number violating parameters set by the unbounded from below directions, and from the absence
of the charge and color breaking minima in this model.
