SUSY QCD corrections to electroweak gauge boson production with an associated jet at the LHC

TL;DR

This paper investigates the impact of supersymmetric QCD corrections on the Drell-Yan process with an associated jet at the LHC, finding negligible effects on total cross sections but small effects at high transverse momentum.

Contribution

It provides the first detailed analysis of O(alpha_s) SQCD corrections to Drell-Yan processes with jets within the MSSM, including decay channels.

Findings

SQCD corrections are negligible for total cross sections.

Percent-level effects appear at high lepton transverse momentum.

The study enhances understanding of supersymmetric effects in standard candle processes.

Abstract

We study the stability of the neutral- and charged-current Drell-Yan process in association with a jet as a standard candle at the LHC under the inclusion of O(alpha_s) supersymmetric QCD (SQCD) corrections within the MSSM. We include the decay of the electroweak gauge boson into dileptons, i.e. we consider the production of charged lepton--anti-lepton or lepton-neutrino final states with one hard jet. We find that the SQCD corrections are negligible for the integrated cross section. Only at high lepton transverse momentum can they induce effects of the percent level.
