Query: Global U(1) Invariance and Mass Scales in Supersymmetry   In a supersymmetric theory with global U(1) invariance, the spontaneous
breaking of the latter without the breaking of supersymmetry is revisited in
the case of the most general superpotential of 3 singlet superfields. The
interesting possibility of having 2 hierarchical mass scales is pointed out,
together with its consequences as applied to the axionic solution of the strong
CP problem.
