Search for low mass SUSY using hadronic top decays in pp collisions at TeV with the CMS detector

An inclusive search for low mass SUSY using the top plus missing transverse energy signature at CMS is presented. A kinematic fit with the top and W masses as constraints is utilized to reconstruct the top in all-hadronic final states. A 5σ excess can be observed with ∼250 pb -1 at a particular low mass SUSY point. With the same analysis selection the 5σ discovery reach contours in the mSUGRA parameter space for 1 and 10 fb -1 are obtained.
