Search for supersymmetry in hadronic final states with MT2

Abstract

We present the results of a search for physics beyond the Standard Model (BSM) using data of 1.1 fb−1 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.
