HIGLU and HDECAY: Programs for Higgs boson production at the LHC and Higgs boson decay widths

The total cross section for neutral Higgs boson production via the gluon fusion mechanism including NLO (two-loop) QCD corrections can be calculated numerically with the program HIGLU within the Standard Model (SM) as well as its minimal supersymmetric extension (MSSM). The program HDECAY determines the decay widths and branching ratios of the Higgs bosons within the SM and the MSSM, including the dominant higher-order corrections. The program is able to calculate the branching ratios of the MSSM Higgs bosons into standard and supersymmetric particles.
