Squark and gluino hadroproduction

TL;DR

This paper reviews the theoretical calculations and predictions for squark and gluino production in high-energy proton collisions, including advanced QCD corrections, to improve accuracy of cross-section estimates at the Tevatron and LHC.

Contribution

It provides comprehensive numerical predictions incorporating next-to-leading order and resummation techniques for squark and gluino pair-production at collider energies.

Findings

Higher-order corrections significantly affect total cross sections.

Theoretical uncertainties are quantified through scale and PDF variations.

Predictions are tailored for Tevatron and LHC energies.

Abstract

We review the theoretical status of squark and gluino hadroproduction and provide numerical predictions for all squark and gluino pair-production processes at the Tevatron and at the LHC, with a particular emphasis on proton-proton collisions at 7 TeV. Our predictions include next-to-leading order supersymmetric QCD corrections and the resummation of soft gluon emission at next-to-leading-logarithmic accuracy. We discuss the impact of the higher-order corrections on total cross sections, and provide an estimate of the theoretical uncertainty due to scale variation and the parton distribution functions.
