In the effective field theory framework, we consider the effect of supersymmetry breaking via gaugino condensation and supergravity in the hidden sector gauge group on the hidden sector vacuum angle θh. The θhparameter dependence of the potential yields phenomenologically acceptable invisible axion solutions if the U(1)Rsymmetry is broken down to a discrete subgroup ZNwith N≥3 (N=4 is marginal). Anomalous U(1) superstring models are good candidates for this invisible axion resolution of the strong CP puzzle.
