Measurement of cross sections for processes involving e + e - Annihilation to hadrons at the VEPP-2M collider

Achasov M. N.

Results obtained by measuring, in experiments at the VEPP-2M e + e - collider with the CMD-2 and SND detectors at the Novosibirsk Institute of Nuclear Physics, cross sections for e + e - → hadrons annihilation processes at energies in the range 360 ≤ s ≤ 1380 MeV are surveyed. The measured cross sections and the vector-meson parameters deduced from an analysis of these cross sections are presented. The cross section for the process e + e - → π + π - is compared with the spectral function for the decay τ - → π - π 0 ν τ. © 2007 Pleiades Publishing, Ltd.
