Description:
The recent LHC discovery of a new particle at 125 GeV has created a flurry of interest in light stop squarks that are found in models of supersymmetry. However, current experimental constraints on stop squarks are fairly weak due to the small production cross-sections and difficult backgrounds. I will talk about using shape analyses based on missing transverse energy distributions to significantly improve the bounds on stop squarks, particularly in what are considered the most difficult to probe regions of parameter space.
