This three-year project is designed to support the CSUDH component of the Super-Kamiokande project during its initial years. CSUDH scientists will contribute to Super-Kamiokande by undertaking two important tasks. First, our scientists will particpate in the analysis of solar neutrino interactions in Super-Kamiokande. Our second task will involve the development of new models and simulations of background events for nucleon decay studies at Super-Kamiokande.
