N2 - The charge asymmetry in the process 푒+⁢푒− →휋+⁢휋−⁢휋0 is studied taking into account a longitudinal polarization of electrons (positrons). The asymmetry arises due to interference of amplitudes corresponding to production of pions in states with charge parity odd and charge parity even. It is a manifestation of 푎1⁡(1260) meson in the intermediate state. Polarization leads to additional correlations in the differential cross section, which simplifies the experimental study of the process.
