CPsuperH2.0: An improved computational tool for Higgs phenomenology in the MSSM with explicit CP violation |
Abstract | ||
|---|---|---|
We describe the Fortran code CPsuperH2.0, which contains several improvements and extensions of its predecessor CPsuperH. It implements improved calculations of the Higgs-boson pole masses, notably a full treatment of the 4×4 neutral Higgs propagator matrix including the Goldstone boson and a more complete treatment of threshold effects in self-energies and Yukawa couplings, improved treatments of two-body Higgs decays, some important three-body decays, and two-loop Higgs-mediated contributions to electric dipole moments. CPsuperH2.0 also implements an integrated treatment of several B-meson observables, including the branching ratios of Bs→μ+μ−, Bd→τ+τ−, Bu→τν, B→Xsγ and the latter's CP-violating asymmetry ACP, and the supersymmetric contributions to the Bs,d0−B¯s,d0 mass differences. These additions make CPsuperH2.0 an attractive integrated tool for analyzing supersymmetric CP and flavour physics as well as searches for new physics at high-energy colliders such as the Tevatron, LHC and linear colliders.1 1The program may be obtained from http://www.hep.man.ac.uk/u/jslee/CPsuperH.html. |
