Abstract: (APS)
We present a simple proof that all Green's functions for nonexceptional Euclidean momenta in any renormalizable (but not superrenormalizable) field theory containing zero-mass particles are infrared finite. We discuss the relationship of a corollary result, that any physical discontinuity of Green's functions is also infrared finite, to the question of quark confinement in non-Abelian gauge theories.- GAUGE FIELD THEORY: NONABELIAN
