NMSSMCALC-nuSS
Calculator of the Complete One-Loop Corrections to the
Higgs Masses and Trilinear Higgs Self-Couplings
in the NMSSM with Extended Neutrino Sector and Inverse Seesaw Mechanism
O(alpha_t (alpha_t +alpha_s)) Two-Loop Higgs Mass Corrections and Higgs Decay Widths
treated as in the original NMSSMCALC

The program package NMSSMCALC-nuSS is based on the original code NMSSMCALC which has been extended to compute the complete one-loop corrections with the contributions stemming from an extended neutrino sector: The NMSSM is extended by six singlet superfields so that through the mixing with three doublet leptonic superfields the non-zero tiny neutrino masses are generated through the inverse seesaw mechanism. The O(alpha_t ( alpha_t + alpha_s)) two-loop corrections and the Higgs decay widths and branching ratios within the CP-conserving and the CP-violating NMSSM are computed as in the original code NMSSMCALC, i.e. without taking into account the new leptonic contributions. The decay calculator is based on an extension of the program HDECAY 6.10.
The program includes the computation of the muon and electron anomalous magnetic moments and of the electric dipole moments.
