Nexttoleadingorder supersymmetric QCD corrections to the tbH{sup } associated production at hadron colliders
Abstract
We present the nexttoleadingorder QCD corrected total cross sections and the distributions of the transverse momenta of the final antibottom quark, top quark, and charged Higgs boson for the processes of pp/pp{yields}tbH{sup }+X in the minimal supersymmetric standard model at Tevatron and CERN LHC. We find that the nexttoleadingorder (NLO) QCD corrections significantly modify the leadingorder distributions of the transverse momenta of final particles (p{sub T}{sup b}, p{sub T}{sup t}, and p{sub T}{sup H{sup }}), and the total NLO QCD corrections reduce the dependence of the cross section on the renormalization and factorization scales; in particular, the NLO QCD corrected cross sections at the LHC are nearly independent of these scales. Our results show that the relative correction is obviously related to m{sub H{sup }} and tan{beta}, and the total NLO QCD relative corrections can be beyond 50% at Tevatron and approach 40% at the LHC in our chosen parameter space.
