abstract

  • We report on a study of the invariant mass spectrum of the hadronic system in the decay τ-→π-π0ντ. This study was performed with data obtained with the CLEO II detector operating at the CESR e+e- collider. We present fits to phenomenological models in which resonance parameters associated with the ρ(770) and ρ(1450) mesons are determined. The π-π0 spectral function inferred from the invariant mass spectrum is compared with data on e+e-π+π- as a test of the conserved vector current theorem. We also discuss the implications of our data with regard to estimates of the hadronic contribution to the muon anomalous magnetic moment. ©2000 The American Physical Society.
