Same-sign Dilepton Signatures of RPV SUSY
Date: Tuesday, March 12th
Time: 4:00 pm
Place: 5280 Chamberlin Hall
Speaker: Joshua Berger, SLAC, Stanford University
Abstract: 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.
