High-statistics measurement of the pion form factor in the process τ−→π−π0ντ

We report a measurement of the invariant mass spectrum of the π−π0 system and the pion form factor |Fπ(s)| for τ−→π−π0ντ using of data recorded with the Belle detector at the KEKB e+e− collider. The unfolded π−π0 mass spectrum is used to determine resonance parameters for the ρ(770), ρ′(1450), and ρ″(1700) mesons. We also use this spectrum to estimate the hadronic contribution to the anomalous magnetic moment of the muon.
