τ → π π π ν<SUB>τ</SUB> decays and the a<SUB>1</SUB>(1260) off-shell width revisited

The τ → π π π ν τ decay is driven by the hadronization of the axial-vector current. Within the resonance chiral theory, and considering the large- N C expansion, this process has been studied in Ref. [1] (D. Gomez Dumm, A. Pich, J. Portoles, 2004). In the light of later developments we revise here t...
