FeynHiggs: A program for the calculation of MSSM Higgs-boson observables – Version 2.6.5

Abstract

FeynHiggs is a Fortran code for the calculation of physical observables in the field of high-energy physics. FeynHiggs calculates various observables in the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM) for real or complex parameters. These observables comprise Higgs-boson masses, mixing angles, couplings, Tevatron/LHC production cross-sections, branching ratios, as well as some additional observables such as Δ ρ, M W , the effective leptonic weak mixing angle, ( g − 2 ) μ , BR( b → s γ ), electric dipole moments.

Phys. Comm. 124 (2000) 76 Does the new version supersede the previous version?: Yes Nature of problem: The experimental searches for Higgs bosons have to be compared with theory predictions at a high level of accuracy. Radiative corrections are especially important in the Minimal Supersymmetric Standard Model (MSSM). Solution method: High-precision calculations (mostly based on the Feynman-diagrammatic approach) for various Higgs-boson observables in the MSSM are implemented. The program takes the basic model parameters as input and evaluates many MSSM Higgs-boson observables relevant for experimental Higgs-boson physics. Reasons for new version: Existing calculations have been refined (e.g., by the inclusion of complex parameters); many new observables have been implemented. Summary of revisions: Input parameters are now allowed to be complex, and non-minimal flavor violation is permitted. Besides the Higgs-boson masses also branching ratios and hadron-collider production cross-sections are calculated. Restrictions: Several observables are still missing and have to be implemented. Running time: The command-line frontend, which invokes essentially all FeynHiggs functions, takes 200 ms a single point in parameter space On a 3 GHz AMD CPU.
