Abstract

By including the effects of superstring thresholds, we reconsider minimal string unification together with the requirement of producing a supersymmetry-breaking gluino condensate in the hidden sector. This gives, for examples of phenomenologically-viable $Z_8'$ and other related orbifolds, the constraint that $0.1215 \leq \alpha_s(M_Z) \leq 0.1270$ . In such models, a hidden photino can be a source of cosmological dark matter detectable by gravitational microlensing.
