Associated production of top squarks and charginos at the CERN LHC in NLO SUSY-QCD

Abstract

We calculate the next-to-leading order inclusive total cross sections for the associated production processes $pp\to {\tilde{t}}_i{\tilde{\chi }}_k^{-}+X$ in the Minimal Supersymmetric Standard Model at the CERN LHC. Our results provide the theoretical predictions for the total cross sections for the above processes. The NLO QCD corrections in general enhance the leading order total cross sections significantly, and vastly reduce the dependence of the total cross sections on the renormalization/factorization scale, which leads to increased confidence in predictions based on these results.
