Query: On The tau --> a sub 1 h nu sub tau Decays   The \tau \to (a_1 h)^- \nu_{\tau} decays of the \tau-lepton are studied using
the method of phenomenological chiral Lagrangians. The expression of weak
hadronic currents between pseudoscalar and axial-vector meson states is
obtained. Calculated partial widths for these decays are compared with the
available experimental data.
