NMHDECAY Computes: masses, couplings and decay widths of all Higgs bosons of the NMSSM. masses of all sparticles In terms of its parameters at the electroweak (or susy breaking) scale: the Yukawa couplings lambda and kappa, the soft trilinear terms A_lambda and A_kappa, and tan(beta) and mu_eff = lambda*S. Higgs spectrum includes leading electroweak corrections, two loop terms and propagator corrections. Computation of the decay widths (momentarily without three body decays):

Checks and constraints Running Yukawa lambda, kappa, Y_t, Y_b, Absence of Landau pole below GUT scale. Physical minimum (global minimum). B physics constraints from b -> s gamma, B -> mu+ mu- and B+ -> tau+ nu_tau. The dark matter relic density can be computed via a link to a NMSSM version of the MicrOMEGAs code. Negative SUSY searches at LEP and the Tevatron, including unconventional channels relevant for the NMSSM. Constraint on masses of SUSY particles checked.

NMSPEC Fortran code for the sparticle and Higgs masses, Higgs decay widthds and couplings in the NMSSM with GUT scale boundary conditions. Soft Susy breaking terms specified at the GUT scale. Exceptions are the soft singlet mass and kappa, that are both determined in terms of the other parameters through the minimization equations of the Higgs potential. The soft Higgs and gaugino masses at the GUT scale can be chosen non-universal, if desired. References: [1] U. Ellwanger and C. Hugonie, arXiv:hep-ph/ arXiv:hep-ph/
