CPsuperH2.3: An updated tool for phenomenology in the MSSM with explicit CP violation
Description
Abstract We describe the Fortran code CPsuperH2.3, which incorporates the following updates compared with its predecessor CPsuperH2.0. It implements improved calculations of the Higgs-boson masses and mixing including stau contributions and finite threshold effects on the tau-lepton Yukawa coupling. It incorporates the LEP limits on the processes ^(e+e-)→^(Hi)Z, ^(HiHj)and the CMS limits on ^(Hi)→ττ obtained from 4.6 fb-^1of data at a center-of-mass energy of 7 TeV. It also includes the dec... Title of program: CPsuperH2.3 Catalogue Id: ADSR_v3_0 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 boso ...
