dc.description.abstract | The hadronization structure of τ-→η(′)π-π0ντ decays is analyzed using chiral perturbation theory with resonances, considering only the contribution of the lightest meson resonances at leading order in the 1/N C expansion. After imposing the asymptotic behavior of vector spectral functions ruled by QCD, unknown effective couplings are determined by fitting the τ-→η(′)π-π0ντ branching ratio and decay spectrum to recent data. Predictions for the partner decay τ-→η(′)π-π0ντ and the low-energy behavior of the cross section σ(e+e -→ηπ +π -) are also discussed. | |
