Description
The production of SUSY particles at the LHC is dominated by processes involving coloured sparticles in the final state. Due to the high importance of these processes for SUSY searches at the LHC, precise theoretical predictions are needed. Higher-order QCD corrections are dominated by large logarithmic terms due to the emission of soft gluons from initial and final state particles. A systematic treatment of these logarithms to all orders in perturbation theory is provided by resummation methods. In this talk we discuss the resummation of soft gluon emission at next-to-leading-logarithmic (NLL) accuracy and beyond for squark and gluino pair-production processes. We present the analytical ingredients needed for the calculation and discuss numerical predictions for the LHC.
