Abstract We provide a detailed description of the Fortran code CPsuperH , a newly-developed computational package that calculates the mass spectrum and decay widths of the neutral and charged Higgs bosons in the Minimal Supersymmetric Standard Model with explicit CP violation. The program is based on recent renormalization-group-improved diagrammatic calculations that include dominant higher-order logarithmic and threshold corrections, b-quark Yukawa-coupling resummation effects and Higgs-boson… Expand

CPsuperH2.3: An updated tool for phenomenology in the MSSM with explicit CP violation

- Physics, Computer Science
- Comput. Phys. Commun.
