Infrared problem and zero-mass limit in a model of non-abelian gauge theory
Infrared divergences of Yang Mills theory are regularized by an explicit mass term for the vector meson. By using the invariance properties under Becchi, Rouet and Stora transformations the authors demonstrate that the theory violates physical unitarity also in the limit of zero mass. (13 refs).
