Pulling out all the stops: searching for RPV SUSY with stop-jets

If the lighter stop eigenstate decays directly to two jets via baryonic R-parity violation, it could have escaped existing LHC and Tevatron searches in four-jet events, even for masses as small as 100GeV. In order to recover sensitivity in the face of increasingly harsh trigger requirements at the LHC, we propose a search for stop pairs in the highly-boosted regime, using the approaches of jet substructure. We demonstrate that the four-jet triggers can be completely bypassed by using inclusive jet-H-T triggers, and that the resulting QCD continuum background can be processed by substructure methods into a featureless spectrum suitable for a data-driven bump-hunt down to 100GeV. We estimate that the LHC 8TeV run is sensitive to 100GeV stops with decays of any flavor at better than 5 sigma-level, and could place exclusions up to 300GeV or higher. Assuming Minimal Flavor Violation and running a b-tagged analysis, exclusion reach may extend up to nearly 400GeV. Longer-term, the 14TeV LHC at 300 fb(-1) could extend these mass limits by a factor of two, while continuing to improve sensitivity in the 100 GeV region.
