Abstract
In the minimum supersymmetric SU(5) GUT, we derive the upper limit on the mass of the color-triplet Higgs multiplets as ≤ 2.4× 1016~ (90 \% C.L.) taking all possible corrections into account in a renormalization group analysis. If the above upper limit is compared with a limit on from the negative search for the proton decay; ≥ 2.0× 1016~ (in which effects of the larger top-quark mass are included), the minimum supersymmetric SU(5) GUT is severely constrained.
