e+e- annihilation into hadrons and exclusive τ decays

Eidelman S. I., Ivanchenko V. N.

New calculations of the branching ratios of the τ-lepton hadronic decays are presented based on the conserved-vector-current hypothesis and the whole bulk of data on electron-positron annihilation into hadrons. Recent results from the Neutral Detector (ND) at VEPP-2M and the DM2 detector at DCI are included. Perspectives of future measurements of hadronic cross sections in Novosibirsk are discussed. © 1991.
