Nature of problem:
The mass spectrum, decay widths and branching ratios of the neutral and charged Higgs bosons in the Minimal Supersymmetric Standard Model with explicit CP violation are calculated. 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 pole-mass shifts. The couplings of Higgs bosons to the Standard Model guage bosons and fermions, to their supersymmetric partners and all the trilinear and quartic Higgs-boson self-couplings are also calculated.

Solution method:
One-dimensional numerical integration for the Higgs-decay modes involving more than one massive gauge boson, iterative treatment of the threshold corrections, and the numerical diagonalization of the neutralino mass matrix.

Restrictions:
Only the dominant leading-order QCD corrections which remain unaffected by CP violation have been included in this version.

Running time:
Less than 0.1 second.
