On the role of the a1(1260) meson in τ→4πντ decay

It is shown that a simple model successfully describing experimental data on the process e+e-→4π can also qualitatively account for the data of CLEOII and ALEPH obtained recently in the decay τ→4πντ. The model is based on the assumption of the a1(1260)π and ωπ dominance as intermediate states. Our observation is in contrast with the claim by ARGUS that the ρ-meson signal in the τ→4πντ decay can not be explained by the a1(1260)π intermediate state.
