Does the new version supersede the previous version?: Yes

Nature of problem:
The calculations of mass spectrum, decay widths and branching ratios of the neutral and charged Higgs bosons in the Minimal Supersymmetric Standard Model with explicit CP violation have been improved. The program is based on renormalization-group-improved diagrammatic calculations that include dominant higher-order logarithmic and threshold corrections, b-quark and τ-lepton Yukawa-coupling resummation effects and improved treatment of Higgs-boson pole-mass shifts. The couplings of the Higgs bosons to the Standard Model gauge bosons and fermions, to their supersymmetric partners and all the trilinear and quartic Higgs-boson self-couplings are also calculated. Also included are a full treatment of the 4 × 4 (2 × 2) neutral (charged) Higgs propagator matrix together with the center-of-mass dependent Higgs-boson couplings to gluons and photons, and an integrated treatment of several B-meson observables. The new implementations include the EDMs of Thallium, neutron, Mercury, Deuteron, Radium, and muon, as well as the anomalous magnetic moment of muon, (gμ - 2), the top-quark decays, improved calculations of the Higgs-boson masses and mixing including stau contributions, the LEP limits, and the CMS limits on Hi → τbarτ. It also implements the decay mode Hi → Zγ and includes the corresponding Standard Model branching ratios of the three neutral Higgs bosons in the array GAMBRN(IM,IWB=2,IH).

Solution method:
One-dimensional numerical integration for several Higgs-decay modes and EDMs, iterative treatment of the threshold corrections and Higgs-boson pole masses, and the numerical diagonalization of the neutralino mass matrix.

Reasons for new version:
Mainly to provide the full calculations of the EDMs of Thallium, neutron, Mercury, Deuteron, Radium, and muon as well as (gμ - 2), improved calculations of the Higgs-boson masses and mixing including stau contributions, the LEP limits, the CMS limits on Hi → τbarτ, the top-quark decays, Hi → Zγ decay, and the corresponding Standard Model branching ratios of the three neutral Higgs bosons.

Summary of revisions:
Full calculations of the EDMs of Thallium, neutron, Mercury, Deuteron, Radium, and muon as well as (gμ - 2). Improved treatment of Higgs-boson masses and mixing including stau contributions. The LEP limits. The CMS limits on Hi → τbarτ. The top-quark decays. The Hi → Zγ decay. The corresponding Standard Model branching ratios of the three neutral Higgs bosons.
