Query: Decaying light particles in the SHiP experiment. II. Signal rate
  estimates for light neutralinos   Considering the supersymmetric models with light neutralino and R-parity
violation, we perform estimates of the signal rate expected at the recently
proposed fixed target SHiP experiment exploiting CERN SPS beam of 400 GeV
protons. We extend the existing studies by introducing new production channels
(in particular through the beauty mesons) and decay modes. We also constrain
model parameter space from analysis of negative results of the CHARM
experiment.
