We study the discovery reach of the gluino (g̃) and the lightest stop squark (t̃1) with baryonic R-parity violation (UDD type) in the context of the minimal supersymmetric standard model (MSSM) at the 14 TeV run of the LHC. We consider the gluino pair production process followed by its decay to a top quark and a real or virtual stop squark. The top quark produced from the decay of the gluino can have sufficient transverse momentum to appear as a single fat jet. We apply the jet substructure technique to tag such a hadronically decaying boosted top quark and find that gluino mass up to 1.65 TeV can be discovered whereas the exclusion limit extends up to 1.9 TeV at the 14 TeV LHC with 300fb-1 luminosity. We also briefly discuss the discovery prospect of the boosted stop squark, which may be identified as a narrow resonance in the jet mass distribution. © 2014 American Physical Society.
