FeynHiggs: overview and old versions

• The real and complex case including Higgs decays: FeynHiggs2.6.1

  This version includes all features ever implemented into FeynHiggs:
  • complete set of one-loop corrections
  • all known two-loop corrections applicable in Feynman-Diagrammatic approach
  • evaluation of the charged Higgs sector
  • evaluation of the theory error of the Higgs masses and mixing angles due to unknown higher-order corrections
  • evaluation of the leading corrections from NMFV models
  • evaluation of the Z-factors needed to obtain correct properties for external (on-shell) Higgs bosons
  • evaluation of all relevant mixing matrices
  • complete set of Higgs decay branching ratios
  • additional couplings: Higgs gauge boson, Higgs self couplings
  • the Higgs production cross section at the Tevatron and at the LHC
  • transistion from on-shell to DRbar (and vice versa) parameters
  • easy link to other Fortran/C++ codes
  • easy link within Mathematica
  • help via man pages
  • SPS benchmark scenarios and Les Houches benchmark scenarios are given as predifined input
  • FH2.2 or higher is able to process Les Houches Accord data
    (see hep-ph/0408283 by T. Hahn)
  • The following check items are evaluated:
    • one- and two-loop contributions to (g-2)_mu, see hep-ph/0312264, hep-ph/0405255 (by S. Heinemeyer, D. Stöckinger, G. Weiglein) for details.
    • one- and two-loop contributions to Delta rho MW and sin²(theta_eff) incl. NMFV effects
    • BR(b -> s gamma) incl. NMFV effects, see hep-ph/0512315 (by T. Hahn, W. Hollik, J. Illana, S. Penaranda) for details.

• The older versions: FeynHiggs2.5, 2.4, 2.3, 2.2, 2.1

  The main differences are:
  • FeynHiggs2.1 requires LoopTools for the evaluation of the involved three point functions.
    LoopTools can be found here.
  • These two codes are in general less advanced, but have gone through more checks
  For FeynHiggs2.5, 2.4, 2.3, 2.2, 2.1, go here.
  
  
  

• The purely real case: FeynHiggs1.5.1

  This is a thoroughly tested but outdated version including
  • all existing (FD) higher-order corrections
  • transistion from on-shell to DRbar (and vice versa) parameters
  • various benchmark scenarios as possible default input
  • evaluation of the leading corrections from NMFV models
  For this code, go here.
  
  
  

• The real case including Higgs decays: FeynHiggsDecay1.5.1

  This is a thoroughly tested version including
  • all FeynHiggs1.5.1 features (except the NMFV option)
  • all relevant decay channels for the neutral Higgs bosons
  For this code, send an email to Sven Heinemeyer.
  Alternative option: use FeynHiggs2.x. It has all the features of FeynHiggsDecay!
