Query: Large Hadron Collider constraints on a light baryon number violating
  sbottom coupling to a top and a light quark   We investigate a model of R-parity violating (RPV) supersymmetry in which the
right-handed sbottom is the lightest supersymmetric particle, and a baryon
number violating coupling involving a top is the only non-negligible RPV
coupling. This model evades proton decay and flavour constraints. We consider
in turn each of the couplings lambda"_{313} and lambda"_{323} as the only
non-negligible RPV coupling, and we recast two recent Large Hadron Collider
(LHC) measurements and searches (CMS top transverse momentum p_T(t) spectrum
and ATLAS multiple jet resonance search) in the form of constraints on the
mass-coupling parameter planes. We delineate a large region in the parameter
space of the mass of the sbottom (m_{b_R}) and the lambda"_{313} coupling that
is ruled out by the measurements, as well as a smaller region in the parameter
space of m_{b_R} and lambda"_{323}. A certain region of the
m_{b_R}-lambda"_{313} parameter space was previously found to successfully
explain the anomalously large ttbar forward backward asymmetry measured by
Tevatron experiments. The entire region is excluded at the 95% CL by CMS
measurements of the top p_T spectrum. We also present p_T(ttbar) distributions
of the forward-backward asymmetry for this model.
