摘要：

We consider the process of associated stop-chargino production in the MSSM at LHC and show that, at the simplest Born level, the production rate is dramatically sensitive to the choice of the benchmark points, oscillating from potentially visible maxima of the picobarn size to much smaller, hardly visible, values. Adopting a canonical choice of SM-type CKM matrices, we also show that in some visible cases the total rate exhibits a possibly relevant dependence on tan beta.
