Bare coupling constants and asymptotic behaviour in reggeon field theory

Abstract

A relation between the values of bare coupling constants and the asymptotic bchaviour of the reggeon field theory (RFT) is discussed. We show how the numerical values of bare coupling constants fix the starting point of renormalization group trajectories which, in turn, determine the asymptotic behaviour of the RFT. We discuss applications to a pure pomeron theory and a pomeron plus f-pole model. Some nontrivial phenomenological information concerning the values of bare triple-Regge pomeron-f-pole coupling constants is obtained.
