A search for SUSY using the top quark plus missing transverse energy (MET), in a low mass mSUGRA test point is performed.A two-constraints kinematic fit is utilized to extract the top quark, either b-jet the ones that is recognizable or it is not recognizable.It is shown that for point LM1, for the former situation, a 5 excess can be achieved with 30 , and for the latter situation, it can be observed with 9.6. The ratio of the final signal over background for both situations is 12.0.
