The role of the rho meson in pion-nucleus interactions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

It is shown that the static model gives a large overestimate of the effects of rho-meson propagation for pionic scattering and reactions at low and medium energies. In a relativistic treatment, the effect of intermediate stateρ-propagation is shown to be small and often negligible within present uncertainties. An improved value for theρNΔ coupling constant is extracted from Ragge pole fits.
