Pion Form Factor Phase, PIon Pion Elasticity and New Electron-Positron Data

Abstract

New precise data on the low energy electron-positron annihilation into hadrons from Novosibirsk are used to obtain bounds on the elasticity parameter and the difference between the phase of the pion form factor and that of pion pion scattering
