NLO distributions for Higgs production at the LHC

Abstract

We report on results for the NLO corrected differential distributions $d\sigma /d{p}_T$ and $d\sigma /dy$ for the process $p+p\to H{+}^{\prime }{X}^{\prime }$, where $p_T$ and $y$ are the transverse momentum and rapidity of the Higgs-boson $H$ respectively and $X$ 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 $m_t\to \infty$. Our calculations reveal that the dominant subprocess is given by $g+g\to H{+}^{\prime }{X}^{\prime }$ but the reaction $g+q(\bar{q})\to H{+}^{\prime }{X}^{\prime }$ is not negligible. Also the $K$-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.
