Anomalies and a possible solution of problems of zero-charge and infra-red instability
Abstract
We discuss a possible solution of the problems of zero-charge in QED and of infra-red instability in QCD. The solution is based on the introduction of extra currents which compensate the Pauli-Villars subtraction in the amplitudes of photon-photon or gluon-gluon scattering.
