| Abstract: Understanding the dynamics of QCD and the effects of confinement is one of the important remaining challenges for standard model physics. Here I will explain how some of these questions can be addressed in a cousin of ordinary QCD which is obtained by starting from a supersymmetric version, and then gradually breaking supersymmetry via anomaly mediation. These theories have phases identical to QCD, though the underlying dynamics causing confinement may be different. Within these theories one can find the eta' potential and theta dependence and address the phase structure of spontaneous CP breaking at theta = Pi. One can also derive the analog of the chiral Lagrangian, and explicitly check the magnitude of a dynamically generated up mass. Surprisingly we find that within these models the dynamically generated up quark mass could be sufficiently large to account for the entire up mass. Link to the Event Video |
