Abstract This article describes the code SusHi (for “ Su per s ymmetric Hi ggs”) [108] which calculates the cross sections p p / p p ¯ → ϕ + X in gluon fusion and bottom-quark annihilation in the SM 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 p T 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, 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 Higgs masses.
