Electroweak contributions to squark-gluino production at the LHC

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(2)(s)alpha), which include real photon and real quark radiation processes. Also considered are photon induced tree level O(alpha(s)alpha) contributions.
