Muon anomalous magnetic moment
New results on the low energy e+e- annihilation into hadrons from Novosibirsk and Beijing are described. The validity of the CVC relation between e+e- and τ decays is considered. Implications of the new measurements for the evaluation of the hadronic contribution to the muon anomalous magnetic moment are discussed.
