Abstract

The widths of the τ → [ρ0(770), ρ0(1450)]π−ντ decays have been calculated within the extended Nambu—Jona-Lasinio model including both the ground and first radially excited intermediate meson states. The axial-vector channel with intermediate a1 mesons dominates. The values of the masses and total widths of the a1 meson recently obtained by the COMPASS and JPAC Collaborations have been taken into account.
