“Repulsive” Potential Approach to Pion Resonances

  • A. N. Mitra

Abstract

I shall be concerned here with a phenomenological approach to pionic interactions that we have been pursuing during the last year in order to understand some of the pion resonances. This approach, which is characterized by low-energy repulsion and high-energy attraction, was motivated through certain manifestations of s- and p-wave π-π interactions. For s-waves, some important manifestations are pion-nucleon scattering1 and τ-decay anomalies. (The results of various approaches to this problem have been summarized by Kacser.2) For p-waves resonances such as ρ, ω, and φ come first to mind.
