Title: THE RENORMALIZATION GROUP METHOD AND HIGH-ENERGY SCATTERING
Abstract: The renormalization group method is used to investigate the behavior of high-energy scattering amplitudes. It is shown that for pion-pion scattering, renormalizability imposes a restriction on the energy and coupling-constant dependence of the high-energy scattering amplitudes at a fixed angle. There is, however, no restriction on the angular dependence at fixed energy and coupling constant, or on the energy dependence at fixed momentum transfer. The method, therefore, is not relevant to the problem of Regge poles. It is further pointed out that the renormalization group method is not applicable to the problem of pionnucleon scattering. These results are in disagreement with those of a number of authors. (auth)
