Search for bottom squarks in the baryon-number violating MSSM

We consider a scenario of Minimal Supersymmetric Standard Model (MSSM) with \(R\)-parity violation, where the lightest supersymmetric particle (LSP) is the lighter sbottom \((\tilde b_1)\). We study the production of a sbottom pair at the LHC and their subsequent decays through the baryon number violating \((U D D)\) operators leading to a top pair with two light quarks. Looking for both semi-leptonic and fully hadronic (no leptons) final states, we perform cut-based as well as multivariate analyses (MVA) to estimate the signal significance at the 13 TeV run of the LHC. We find that a cut-based analysis can probe sbottom mass upto \(\sim 650 \) GeV which may be extended upto \(\sim 750 \) GeV using MVA with \(300~{\rm fb}^{-1}\) integrated luminosity. The fully hadronic final state, however, is not as promising.
