Distributions for MSSM Higgs boson + jet production at hadron colliders

Oliver Brein, Wolfgang Hollik

TL;DR

The paper provides a detailed calculation of pseudorapidity and transverse-momentum distributions for MSSM $h^0$ production in association with a high-$p_T$ jet at the LHC and Tevatron, comparing with the SM across several benchmark scenarios. It shows that for large $m_A$ loop-induced processes and light superpartners can modify both rates and shapes, while for small $m_A$ enhanced $b$-quark Yukawa couplings lead to dominant tree-level contributions and dramatically larger cross sections with central jets. The work combines partonic-process analysis, hadronic convolution with MRST PDFs, and realistic cuts to quantify MSSM effects on differential observables, highlighting potential experimental signatures. Overall, the results illuminate how MSSM parameters and superpartner spectra imprint measurable differences on Higgs+jet distributions, informing collider searches and interpretation.

Abstract

We present pseudorapidity and transverse momentum distributions for the cross section for the production of the lightest neutral Higgs boson in association with a high-p_T hadronic jet, calculated in the framework of the minimal supersymmetric standard model (MSSM). We discuss the theoretical predictions for the differential cross sections at the Large Hadron Collider and the Tevatron for the most common benchmark scenarios.
