On the consistency of electromagnetic form factors and ππ scattering in the ρ(1600) region

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A two channel doubly-subtracted dispersion relation representation of the 2π and 4π electromagnetic form factors is constructed from a predetermined two-channel ρ-wave ππ-scattering amplitude. We find that a good representation of the pion form factor can be achieved but only at the expense of theF 4π form factor. It seems to be difficult to reconcile all of the data in the ρ(1600) region within a two resonance framework indicating additional rho-like resonant structure in this energy region.
