Fermion renormalized vertex functions, effective mass, and condensate in an external Yang-Mills gauge field

We investigate the renormalized fermion-gluon vertex, the fermion effective mass, and the fermion condensate when the fermion propagates in an external Yang-Mills gauge field. We use an exact Green’s function for the Dirac operator in a non-Abelian plane-wave gauge field to const...
