Schwinger- Dyson Equations and Dynamical Symmetry Breaking in Quantum R^2- gravity

High Energy Physics - Theory 2007-05-23 v1

Abstract

The dymamical chiral symmetry breaking in higher- derivative quantum gravity has been investigated on the flat background. The Schwinger- Dyson equations numerical solutions have been found in the ladder approximation. Both two- and four- dimensional cases have been considered. The dymamical fermion mass generation accompanied by the second- order phase transition has been shown to take place in a different gauges.
