We make a detailed analysis on the nucleon decay in the minimal super-symmetric SU(5) grand unified model. We find that a requirement of the unification of three gauge coupling constants leads to a constraint on a mass M H C of color-triplet Higgs multiplet as 2×10 13 GeV ≤ M H C ≤ 2×10 17 GeV, taking both weak-and GUT-scale threshold effects into account. Contrary to the results in the previous analyses, the present experimental limits on the nucleon decay turn out to be consistent with the… CONTINUE READING
