CVC and hadronic decays of τ lepton

Eidelman S. I., Ivanchenko V. N.

Critical analysis of the tests of the conserved vector current (CVC) using data on τ-lepton decays into hadrons and e+e- → hadrons is presented. CVC predictions for the branching ratios and mass spectra derived from e+e- data are in general consistent with the data on τ decays. Limitations on the precision of CVC tests resulting from the available statistics are discussed.
