Sgoldstino interpretation of HyperCP events

We discuss possible sgoldstino interpretation of the observation, reported by HyperCP collaboration, of three Sigma (+) -> p mu (+) mu (-) decay events with dimuon invariant mass 214.3 MeV within detector resolution. We find that this interpretation is consistent in models with (i) parity conservation in sgoldstino interactions, (ii) pseudoscalar sgoldstino P of mass 214 MeV and heavier scalar sgoldstino, and (iii) low supersymmetry breaking scale, root F = 2.5-6.0 TeV. In these models, sgoldstino can be observed in decays K (+) -> pi(+) pi(0) P, K-L -> pi pi P and K-S -> pi pi P at the branching ratios of at least of order 10(-12), 10(-8) and 10(-11), respectively. The model can be probed also at e(+) e(-) colliders in the channels e(+)e(-) -> gamma P and e(+) e(-) -> e(+) e(-) P, where the cross section is likely to be in the range 1 pb-5 ab.
