  We present the results of a search for physics beyond the Standard Model
(BSM) using data of 1.1 /fb integrated luminosity collected by the CMS
experiment at the LHC. Fully hadronic final states were selected based on the
"stransverse" mass variable MT2 and interpreted in various models of
supersymmetry (SUSY). Two complementary analyses were performed targeting
different areas of the SUSY phase space. All backgrounds were estimated using
both simulation and data-driven methods. As no excess of events over the
expected background was observed exclusion limits were derived.
