Decaying light particles in the SHiP experiment. III. Signal rate estimates for scalar and pseudoscalar sgoldstinos

For supersymmetric extensions of the Standard Model with light sgoldstinos - scalar and pseudoscalar superparthners of goldstino - we estimate the signal rate anticipated at the lately proposed fixed target experiment SHiP utilizing CERN SPS beam of 400 GeV protons. We also place new limits on the model parameters from the similar analysis of the published results of CHARM experiment.
