MULTI-POMERON COUPLINGS TO EXTERNAL PARTICLES IN REGGEON FIELD-THEORY

Summary:We show that, contrary to previous assertions, multi-pomeron couplings to the external particles are equally as important as single couplings in the asymptotic behaviour of the amplitude in the reggeon calculus. Our arguments require a careful discussion of the relation of the reggeon calculus to a renormalizable field theory and of the renormalization of composite operators in reggeon field theory. © 1978.
