Softly Broken MQCD and the Theta Angle

We consider a family of non-supersymmetric MQCD five-brane configurations introduced by Witten, and discuss the dependence of the curves on the microscopic Theta angle and its relation with CP. We find evidence for a non-trivial spectral-flow of the curves (vacua) and for the level-crossing of adjac...

description We consider a family of non-supersymmetric MQCD five-brane configurations introduced by Witten, and discuss the dependence of the curves on the microscopic Theta angle and its relation with CP. We find evidence for a non-trivial spectral-flow of the curves (vacua) and for the level-crossing of adjacent curves at a particular value of the Theta angle, with spontaneous breaking of CP symmetry, providing an MQCD analog of the phase transitions in Theta proposed by 't Hooft.
