We use heavy vector meson SU(2)L×SU(2)R chiral perturbation theory to predict differential decay distributions for τ→ρπντ and τ→K*πντ in the kinematic region where pV·pπ/mV (here V=ρ or K*) is much smaller than the chiral symmetry-breaking scale. We also predict the rate for τ→ωπντ in this region (now V=ω). Comparing our prediction with experimental data, we determine one of the coupling constants in the heavy vector meson chiral Lagrangian.
