Search for Direct Stop Production Using the Razor Variables with the CMS Experiment at the CERN LHC
MetadataShow full item record
A search for supersymmetry in the context of direct stop production is presented using the the full 19/fb dataset collected in 2012 by the Compact Muon Solenoid experiment at the Large Hadron Collider with a center of mass energy of 8 TeV. This analysis makes use of the razor kinematic variables, aimed at formulating searches for new physics as a resonance search, despite the lack of constraints from missing momentum due to new physics particles escaping the detector unseen. In the absence of a signal, upper limits on allowed cross sections are derived, resulting in excluded masses for stops and neutralinos (assumed to be the lightest supersymmetric particle).
