It takes into account contributions of the different processes. The dependence of the decay width and various asymmetries on the electron-positron invariant mass was calculated. Differential decay width, fraction of the longitudinal polarization of K - meson, transverse asymmetry and forward-backward asymmetry are compared with experiment from Belle (KEKB) and CDF (Tevatron). Predictions for experiments LHCb were made. The analytical expressions for the Stokes parameters of relativistic positron channeling in crystals were obtained and the corresponding numerical program were developed for the calculation of the polarization characteristics.
