Abstract
We review various ways of obtaining consistency between the idea of su persymmetric grand unification and an apparent low value of alpha(s) s imilar to 0.112 indicated by several low energy experiments. We argue that to reconcile the low value of alpha(s) with the predictions of su persymmetric GUT's, we need to go beyond the standard minimal supersym metric GUT scenario and invoke new physics either at 10(11)-10(12) GeV or at the GUT scale.
