QUARK CONDENSATES IN NONSUPERSYMMETRIC MQCD

A set of non-supersymmetric minimal area embeddings of an M-theory 5-b rane are considered. The field theories on the surface of the 5-brane have the field content of N = 2 SQCD with fundamental representation m atter fields. By suitable choice of curve parameters the N = 2 and N = 1 superpartners may be decoupled leaving a semi-classical approximati on to QCD with massive quarks. As supersymmetry breaking is introduced a quark condensate grows breaking the low energy Z(F) flavour symmetr y. At theta = (odd) pi spontaneous CP violation is observed consistent with that of the QCD chiral lagrangian. (C) 1998 Elsevier Science B.V .
