Unlike all the previous studies on proton decay which worked only in the Minimal Supersymmetric Standard Model, we study the effects of the dimension-5 operators in the Supersymmetric Unification Models with left–right symmetry at low energy. The full chargino sector is used for the analysis. Dressing of the RRRR operators by the SU (2)R wino makes important or even dominant contributions to the proton decay modes into charged leptons.

Lower Limits

We have analyzed 1144 days of Super-Kamiokande data for 13 of the more than 40 possible nucleon decay modes. We have studied p→e+π0, and twelve other two particle B-L conserving decay modes including those with kaons that are preferred in supersymmetric theories. Most modes are currently free of candidate events. In all cases the number of candidates is consistent with atmospheric neutrino induced backgrounds. We have calculated 90% confidence level single sided lower limits on the lifetime of the neutron and proton (divided by the unknown branching ratio) for the studied modes. All of our lower limits are higher than previous best limits by a factor of 2-10. Our limit for p→e+π0 is now 4.4×1033 years.
