Condition on the symmetry-breaking solution of the Schwinger-Dyson equation
arXiv:hep-th/0102206 · doi:10.1063/1.532205
Abstract
We derive a condition for a nontrivial solution of the Schwinger-Dyson equation to be accompanied by a Goldstone bound state. It implies that, for quenched planar QED, although chiral symmetry breaking occurs when there is a cutoff, the continuum limit fails to exist.
