Abstract

We show that the asymmetry in $e + \bar{e} \to 2 π, 3 π$ , due to interference between one-photon and two-photon terms is quite large near the $f$ , $A_{1}$ , and $A_{2}$ resonance positions, but goes through a zero. The analysis of this asymmetry can yield important information about the resonances and theories describing them.
