Abstract :
By considering the constraints from nucleon decay we obtain upper limits on tanβ in generalized supersymmetric SU(5) grand unified theories with gauge-mediated supersymmetry breaking. We find that the predicted values of tanβ in these models are mostly inconsistent with the constraints from nucleon decay.
