Abstract

We consider a scenario of a minimal supersymmetric standard model with R-parity violation, where the lightest supersymmetric particle is the lighter bottom squark (b-1). We study the production of a bottom squark pair at the LHC and their subsequent decays through the baryon number violating operators leading to a top pair with two light quarks. Looking for both semileptonic 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 bottom squark mass up to ∼750 GeV, which may be extended up to ∼850 GeV using MVA with 300 fb-1 integrated luminosity. The fully hadronic final state, however, is not as promising.
