Stop production at hadron colliders Original Research Article

Stop particles are expected to be the lightest squarks in supersymmetric theories and the search for these particles is an important experimental task. We therefore present the cross sections for the production processes pp/pp → t̃1t̃1 and t̃2t̃2 at Tevatron and LHC energies in next-to-leading order supersymmetric QCD. The corrections stabilize the theoretical predictions for the cross sections, and they are positive, thus raising the cross sections to values above the leading-order predictions. Mixed t̃1t̃2/t̃1t̃2 pairs can only be generated in higher orders at strongly suppressed rates.
