Abstract
Models of strongly interacting theories with a large mass anomalous dimension () provide an interesting possibility for the dynamical origin of the electroweak symmetry breaking. A laboratory for these models is QCD with many flavors, which may present a nontrivial fixed point associated to a conformal region. Studies based on conformal field theories and on Schwinger-Dyson equations have suggested the existence of bounds on the mass anomalous dimension at the fixed points of these models. In this note we discuss values of multiflavor QCD exhibiting a nontrivial fixed point and affected by relevant four-fermion interactions.
