Heavy-flavor effects in supersymmetric Higgs boson production at hadron colliders

Abstract

We evaluate the effect of the bottom-quark mass on resummed transverse momentum distributions of supersymmetric Higgs bosons at the Tevatron and LHC. The mass of the bottom quark acts as a non-negligible momentum scale at small transverse momenta and affects resummation of soft and collinear radiation in this region. The improved treatment of the b-quark mass and kinematical effects lead to observable modifications in the resummed predictions for both colliders.
