SUMMARY:Same-sign Dilepton Signatures of RPV SUSY\, Theory Seminar (High Energy/Cosmology)\, Joshua Berger\, SLAC\, Stanford University
DESCRIPTION:The lack of observation of superpartners at the Large Hadron Collider so far has led to a renewed interest in supersymmetric (SUSY) models with R-parity violation (RPV).  With the additional assumption of holomorphic Minimal Flavor Violation (MFV)\, baryonic RPV dominates and the strongest bounds can be evaded.  I demonstrate the sensitivity of same-sign lepton searches at the LHC to MFV/RPV SUSY in two different scenarios.  In the first\, production of neutral "mesinos" which oscillate yields an observable signature.  In the second\, production of Majorana gluinos generates same-sign leptons with large production cross-section.  I reinterpret current results to place bounds on these scenarios and discuss methods to enhance the signature in future searches.
