Squark anti-squark pair production at the LHC: the electroweak contribution

Abstract

We present the complete NLO electroweak contribution of $\mathcal{O}({\alpha }_s^2\alpha )$ to the production of diagonal squark--anti-squark pairs in proton--proton collisions. Compared to the lowest-order $\mathcal{O}({\alpha }_s\alpha +{\alpha }^2)$ electroweak terms, the NLO contributions are also significant. We discuss the LO and NLO electroweak effects in cross sections and distributions at the LHC for the production of squarks different from top squarks, in various supersymmetric benchmark scenarios.
