Using Gauge Coupling Unification and Proton Decay to Test Minimal Supersymmetric SU(5)

John S. Hagelin, S. Kelley, Veronique Ziegler

We derive a one-loop expression, including all thresholds, for the mass of the proton decay mediating color triplets, $M_{D^c}$, in minimal supersymmetric SU(5). The result for $M_…
