SusHi 1.1.1: A program for the calculation of Higgs production in gluon fusion and bottom-quark annihilation in the Standard Model, the 2HDM and the MSSM

This article describes the code SusHi (for “Supersymmetric Higgs”) [1] which calculates the cross sections pp/pp → φ + X in gluon fusion and bottom-quark annihilation in the SM, the 2HDM and the MSSM, where φ is any of the neutral Higgs bosons within these models. Apart from inclusive cross sections up to NNLO QCD, differential cross sections with respect to the Higgs transverse momentum pT and (pseudo-)rapidity y(η) can be calculated through NLO QCD. In the case of gluon fusion, SusHi contains NLO QCD contributions from the third family of quarks and squarks, NNLO corrections due to top-quarks, approximate NNLO corrections due to top-squarks (for the MSSM), and electro-weak effects. It supports various renormalization schemes for the sbottom sector and the bottom Yukawa coupling, as well as resummation effects of higher order tan β-enhanced sbottom contributions. SusHi provides a link to FeynHiggs for the calculation of the MSSM Higgs masses. For calculations in the 2HDM SusHi can be linked to 2HDMC.
