NLO QCD bottom corrections to Higgs boson production in the MSSM

Understand

We present a calculation of the two-loop bottom-sbottom-gluino contributions to Higgs boson production via gluon fusion in the MSSM.

• The calculation is based on an asymptotic expansion in the masses of the supersymmetric particles, which are assumed to be much heavier than the bottom quark and the Higgs bosons.
• We obtain explicit analytic results that allow for a straightforward identification of the dominant contributions in the NLO bottom corrections.
• We emphasize the interplay between the calculations of the masses and the production cross sections of the Higgs bosons, discussing sensible choices of renormalization scheme for the parameters in the bottom/sbottom sector.
