| contents | In a supersymmetric model with low scale supersymmetry breaking light sgoldstinos can appear in decays of mesons abundantly produced in atmospheric showers. We obtain bounds on parameter space of such a scenario from the Super-Kamiokande atmospheric neutrino oscillation data and estimate future sensitivity of the Hyper-Kamiokande project. We find that the bounds from the Super-Kamiokande results are weaker than constraints from existing searches by other experiments while the Hyper-Kamiokande detector can probe a still allowed part of the model parameter space. |
