Abstract
We review various ways of obtaining consistency between the idea of supersymmetric grand unification and an apparent low value of indicated by several low energy experiments. We argue that to reconcile the low value of with the predictions of supersymmetric GUTs, we need to go beyond the standard minimal supersymmetric GUT scenario and invoke new physics either at GeV, or at the GUT scale.
