Quark Condensates in Non-Supersymmetric MQCD
Abstract
A set of non-supersymmetric minimal area embeddings of an M-theory 5-brane are considered. The field theories on the surface of the 5-brane have the field content of N=2 SQCD with fundamental representation matter fields. By suitable choice of curve parameters the N=2 and N=1 superpartners may be decoupled leaving a semi-classical approximation to QCD with massive quarks. As supersymmetry breaking is introduced a quark condensate grows breaking the low energy ZF flavour symmetry. At θ = (odd) π spontaneous CP violation is observed consistent with that of the QCD chiral lagrangian.
