Review of e+e- interactions

A review on e+e- interactions was presented. Electron-positron annihilation in the GeV range has been stUdied in storage rings some characteristics of which including experimental installations were discussed. The pure theory of the e+e- electromagnetic interaction and the one-photon annihilation in the lowest order of e+e- scattering processes are considered. At low energy rho, ω, phi vector meson production is dominated in the e+e- annihilation. At high energy general features of hadron production such as cross sections, multiplicities, average energies, angular distributions and characteristics of inclusive particle spectra are described in detail. Particular attention was paid to J/psi, psi' and other vector meson production and their characteristics: production cross sections particle widths and decay properties. The observed vector mesons are compared with vector state levels predicted by the charmonium model. Between I/psi and approximately 4.6 GeV the number of vector states known at present agrees with the number of states expected by the theory. Experimental data on charm meson and r heavy lepton production and decay are summarized in the review
