Abstract
Finite-size studies of noncompact quantum electrodynamics with four species of almost massless fermions suggest that there is an ultraviolet-stable, nonperturbative fixed point in four dimensions which describes an interacting field theory of bound states. This theory may be relevant to grand unification schemes, technicolor, and recent anomalous heavy-ion experiments.
