New: Higgs masses in the CP-violating high-scale NMSSM
based on EFT pole-mass and quartic-coupling matching
at one-loop order and MSSM-limit 2-loop order

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. In the high-scale NMSSM, the SM-like Higgs mass is derived in the EFT approach based on pole-mass and quartic-coupling matching at full one-loop and MSSM-limit two-loop order.
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.
