We study the IR fate of Chiral Gauge Theories through functional methods and the Effective Average Action. Our results show a rich structure, from the existence of IR conformality to new patterns of Chiral Symmetry Breaking.
We carry out a detailed analysis of the region slightly outside the conformal window of a non-trivial infrared fixed point in a generic bottom-up holographic setup. We focus on models, which study the dynamics of a scalar field, dual to quark degrees of freedom, in a (nearly) AdS geometry. Such models realize the picture expected for vector-like near-conformal theories from Dyson-Schwinger...
I will describe a model of hybrid inflation coming from a general composite theory. Starting from an effective chiral Lagrangian with a dilaton and pions, we identify inflation occurring during the walking dynamics of the theory. A Z2 symmetry-breaking term in the pion sector induces a shift in the inflaton’s trajectory, which leads to a tachyonic instability phase. Curvature perturbations...
