Predictions for orientifold field theories from type 0′ string theory

Two predictions about finite-N non-supersymmetric “orientifold field theories” are made by using the dual type 0′ string theory on C3/Z2×Z2 orbifold singularity. First, the mass ratio between the lowest pseudoscalar and scalar color-singlets is estimated to be equal to the ratio between the axial anomaly and the scale anomaly at strong coupling, M−/M+∼C−/C+. Second, the ratio between the domain wall tension and the value of the quark condensate is computed.
