Description

We discuss the dynamics and phases of a large class of chiral varieties of QCD. We find that the requirement of the correct realization of chiral symmetries in the infrared is sometimes so strong that it virtually determines the dynamics and phase of the system. In the models considered no gauge-invariant bi-fermion condensates exist, and yet in most cases the assumption of confinement and unbroken flavor symmetries leads to a conflict with the anomaly matching requirement. Partial color-flavor locking and dynamical Abelianization emerge as possible mechanisms governing the dynamics of these systems. Possible implications to the real-world theory of fundamental interactions are discussed.
