Abstract

We review recent results on higher-order calculations to squark and gluino production and decay at the LHC, as obtained within the Collaborative Research Centre / Transregio 9 "Computational Particle Physics". In particular, we discuss inclusive cross sections, including the summation of threshold corrections, higher-order calculations for specific squark production channels and for top squark decays, and next-to-leading order calculations for exclusive observables matched to parton showers.
