Abdelhak Djouadi, Michael Spira
TL;DR
This paper investigates the impact of next-to-leading order SUSY-QCD corrections, including virtual squark and gluino exchanges, on Higgs boson production at hadron colliders, finding these effects to be generally small.
Contribution
It provides the first detailed analysis of SUSY-QCD corrections to various Higgs production processes at colliders, incorporating virtual squark and gluino effects.
Findings
Corrections are small at Tevatron and LHC.
Genuine supersymmetric effects are included.
Impacts on Higgs-strahlung, Drell-Yan, and vector boson fusion are analyzed.
Abstract
We analyze the next-to-leading order SUSY-QCD corrections to the production of Higgs particles at hadron colliders in supersymmetric extensions of the Standard Model. Besides the standard QCD corrections due to gluon exchange and emission, genuine supersymmetric corrections due to the virtual exchange of squarks and gluinos are present. At both the Tevatron and the LHC, these corrections are found to be small in the Higgs-strahlung, Drell-Yan-like Higgs pair production and vector boson fusion processes.
