Inclusive search for SUSY in top final states at CMS

An inclusive search for low mass SUSY using the top plus missing transverse energy signature at CMS is presented. A 5$\sigma$ excess can be observed with $\sim$250 pb$^{-1}$ at a particular low mass SUSY point. With the same analysis selection the 5$\sigma$ discovery reach contours in the mSUGRA parameter space for 1 and 10 fb$^{-1}$ are obtained.
