Nature of problem:
Computation of the Higgs and sparticle spectrum in the NMSSM and check of theoretical and experimental constraints.
Mass matrices including up to 2 loop radiative corrections for the Higgs bosons and all sparticles are computed and diagonalized. All Higgs decay widths are computed and branching ratios are compared to experimental bounds. Renormalisation group equations are integrated up to the GUT scale using a modified Runge-Kutta method, in order to check for the absence of a Landau pole. A modified version of MicrOmegas 1.3 can be called in order to compute the relic density of the lightest sparticle.
Reasons for new version:
Higgs to sparticle decays added, computation of dark matter relic density added.
Summary of revisions:
Treatment of RGEs and radiative corrections improved, Higgs to sparticle decays added, new link to MicrOmegas 1.3.
This program supersedes a previous version published in the Journal of High Energy Physics (JHEP 0502:066,2005). The original program is not available from the CPC Program Library.
