| Abstract | |
Models of strongly interacting theories with a large mass anomalous dimension (gamma(m)) 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 gamma(m) values of multiflavor QCD exhibiting a nontrivial fixed point and affected by relevant four-fermion interactions. (AU) | |
