Some Recent Work on Zero Mass Field Theories

Part of the Studies in the Natural Sciences book series (SNS, volume 11)


Some new results on the zero mass behavior of renormalizable field theories are reviewed. Much of the work is directed toward the problem of defining finite transition probabilities in theories with coupled massless fields. In particular, it has been shown through lowest non-trivial order that the production, scattering and detection (with finite energy resolution) of massive quarks in the unbroken SU(3) color gauge model is free of infrared divergences in perturbation theory.
