NMSSMCALC
Calculator of One-Loop and
O((alpha_t + alpha_lambda + alpha_kappa)^2 + alpha_t alpha_s) Two-Loop
Higgs Mass Corrections
and of Higgs Decay Widths
in the CP-conserving and the CP-violating NMSSM
New: Computation of the Loop-Corrected Effective Higgs Self-Couplings and the Loop-Corrected Higgs-to-Higgs Decays up to O(alpha_s*alpha_t + alpha_t^2)

The program package NMSSMCALC calculates the one-loop and O((alpha_t + alpha_lambda + alpha_kappa)^2 + alpha_t alpha_s) corrected Higgs boson masses and the Higgs decay widths and branching ratios within the CP-conserving and the CP-violating NMSSM.
The decay calculator is based on an extension of the program HDECAY 6.10 now. The program also provides the options to calculate the electron and muon anomalous magnetic moments and, in the CP-violating case, the electric dipole moments. The effective loop-corrected trilinear Higgs self-couplings and loop-corrected Higgs-to-Higgs decays are provided up to O(alpha_s*alpha_t + alpha_t^2).
