My research will focus on exploring both R-parity conserving and RPV MFV SUSY in detail. I hope to develop an analytical method to detect certain signal SUSY events with ttbar background, such as a RPV gluino decay to a top, bottom, and strange quark. This involves implementing a new razor-like analysis and developing various fit models, which will help us set new limits for SUSY models such as RPV Gtbs, T2bw, and T2tt.
