NLO distributions for Higgs production at the LHC

Abstract

We report on results for the NLO corrected differential distributions dσ/dpTd\sigma/dp_T and dσ/dyd\sigma/dy for the process p+pH+Xp + p\to H + 'X', where pTp_T and yy are the transverse momentum and rapidity of the Higgs-boson HH respectively and XX denotes the inclusive hadronic state. All QCD partonic subprocesses have been included. The computation is carried out in the limit that the top-quark mass mtm_t \to \infty. Our calculations reveal that the dominant subprocess is given by g+gH+Xg + g \to H + 'X' but the reaction g+q(qˉ)H+Xg + q(\bar q) \to H + 'X' is not negligible. Also the KK-factor representing the ratio between the next-to-leading order and leading order differential distributions varies from 1.4 to 1.7 depending on the kinematic region and choice of parton densities.
