SUSY Searches with Opposite Sign Dileptons at CMS

A full simulation study with the detector CMS is presented. The Leptons + Jets + Missing Energy (l = e,$\\mu$) final state for SUSY events is investigated at mSUGRA benchmark point LM1. The end point in the dilepton pair invariant mass distribution is reconstructed and a scan of the $\\left(m_{0},\\, m_{1/2}\\right)$ plane is performed in order to determine the observability reach.
