Calculable observables in quantum chromodynamics I
A simple heuristic proof of infrared finiteness to all orders of perturbation theory is given for a class of observables in massless field theories including quantum chromodynamics. This class includes the average energy E( Omega ) carried into a given solid angular region Omega by final-state parti...
