Description
The recently proposed RPV (P-parity violation) natural SUSY framework indicates that supersymmetry could have escaped from the current SUSY searches, based on a large missing energy, and hide in very jetty environments while remaining as well-motivated stabilization mechanisms. As an interesting case I will talk about a stop LSP scenario and its test at the LHC8 via gluino cascades. In this process stops and tops are produced from gluino pair and stops further decay to jets via UDD type RPV couplings, resulting in lepton + jets signature. I will demonstrate our two-layered search strategy that consists of (1) a simple cut-and-count analysis, based on HT and jet multiplicity, and (2) stop mass reconstruction by the detailed kinematics and jet substructure, and talk about its reach sensitivity at LHC8 with 20/fb.
