Description
Gauge-fermion theories and their IR fate remain puzzling mysteries in QFT, even after decades of study. Beyond their theoretical interest, they could play a natural role in extensions of the SM, such as GUTs, dynamical symmetry breaking, and models of quark and lepton substructure. Yet our ignorance of these models severely hampers their potential application to realistic theories of nature. Therefore, it is of utmost importance to gain knowledge about their dynamics. By use of functional methods and the Effective Average Action we investigate for the first time from first principles the IR of a particular class of Chiral Gauge Theories [1,2]. Our results show a rich structure, from the existence of IR conformality to new patterns of Chiral Symmetry Breaking.
