Abstract

We have studied the τ→νρ⁰π decay in data taken with the PLUTO detector at the DORIS e⁺e^- storage ring, at CM energies from 4 to 5 GeV. We have found 27 events with the τ→νρ⁰π decay mode corresponding to a branching ratio of B=(5.4±1.7)%. The Dalitz plot and the ρ⁰π mass spectrum are analysed for the ρπ partial wave and spin state. Only the ρ⁰πs-wave as produced by the axial vector current gives a good description. The ρ⁰π mass spectrum is suggestive of an A₁ resonance. An upper limit on τ^±→vπ^±π⁺π^- without ρ⁰ formation is given.
