Observation of multihadronic events in e^+e^- collisions at the energy of 1.18-1.34 GeV

Using the electron-positron storage ring VEPP-2 multipionic events have been observed at a total energy of 1.18-1.34 GeV. The experimental cross-section appears to be considerably larger than calculated within the framework of the vector dominance model for the processes e^+e^- -> π, ε, ωπ, A&quo...

Using the electron-positron storage ring VEPP-2 multipionic events have been observed at a total energy of 1.18-1.34 GeV. The experimental cross-section appears to be considerably larger than calculated within the framework of the vector dominance model for the processes e^+e^- -> π, ε, ωπ, A"1π. The data on the total cross-section obtained in the framework of the statistical model with 4 pions are presented. Ausführliche Beschreibung
