In this paper we present an analysis at NLO QCD of the contribution from squark-squark production to the experimental signature with opposite-sign same flavor leptons, taking into account decays and experimental cuts. We consider the case in which one squark decays directly into the lightest neutralino and the other one into the second lightest neutralino and subsequently into via an intermediate slepton. On the one hand we study the effects of the NLO corrections on invariant mass distributions which can be used for future parameter determination. On the other hand we analyze the impact on predictions for cut-and-count searches using the given experimental signature.
