Wolfgang Hollik, Edoardo Mirabella, Maike K. Trenkel
TL;DR
This paper calculates the electroweak corrections to squark-gluino production at the LHC within the MSSM, including NLO EW effects and photon-induced processes, providing more precise theoretical predictions.
Contribution
It presents the first complete NLO electroweak corrections for squark-gluino production, incorporating real photon, quark radiation, and photon-induced contributions.
Findings
Electroweak corrections significantly affect production cross sections.
Photon-induced processes contribute notably at NLO.
Results improve the accuracy of theoretical predictions for LHC searches.
Abstract
We calculated the electroweak contributions to the hadronic production of a squark in association with a gluino within the Minimal Supersymmetric Standard Model (MSSM). Presented are complete next-to-leading order electroweak (NLO EW) corrections at O(alpha_s^2 alpha), which include real photon and real quark radiation processes. Also considered are photon induced tree level O(alpha_s alpha) contributions.
