Search for Supersymmetry in the Same-Sign Dilepton Channel with the CMS detector

Events with same-sign dileptons, high $p_T$ multijets and large missing energy represent a very low Standard Model background at the LHC. In regions of the Supersymmetry parameter space which are accessible in the first $100$ $pb^{-1}$ of integrated luminosity, there are expected to be low momentum leptons which are not strongly isolated from the rest of the event. Using a pseudo-data sample of 10 TeV pp collisions reconstructed by a full simulation of the CMS detector, we will present a search for an excess of low momentum same-sign dilepton events over a data driven estimate of the background.
