NMSSMCALC

Calculator of One-Loop and
O(αt αs + (αt + αλ + ακ)2) Two-Loop
Higgs Mass Corrections
and of Higgs Decay Widths
in the CP-conserving and the CP-violating NMSSM

Computation of the Loop-Corrected Effective Higgs Self-Couplings
and the Loop-Corrected Higgs-to-Higgs Decays
up to O(αt αs + αt2)


Computation of the muon anomalous magnetic moment and the electric dipole moment

New: Computation of the ρ parameter up to O(α + αt αs + (αt + αλ + ακ)2)); W-mass prediction in the SM, at 1-loop NMSSM, 2-loop QCD NMSSM, 2-loop EW NMSSM

The program package NMSSMCALC calculates the one-loop and O(αt αs + (αt + αλ + ακ)2) 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 effective loop-corrected trilinear Higgs self-couplings and loop-corrected Higgs-to-Higgs decays are provided up to O(αt αs + αt2).
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 program provides the ρ parameter up to O(α + αt αs + (αt + αλ + ακ)2); the W-mass prediction in the SM, at 1-loop NMSSM, 2-loop QCD NMSSM, 2-loop EW NMSSM.
