  "abstract": "Axial-vector mesons $a_1(1260)$, $f_1(1285)$, $h_1(1170)$, $K_1(1270)$, and $K_1(1400)$ can be produced in semileptonic $\\tau\\to A P \\nu_{\\tau}$ decays, where $P$ stands for the pseudoscalar mesons $\\pi$ or $K$. We calculate the branching ratios based in a meson dominance model. The exclusive channels $\\tau^-\\to a_1(1260)^-\\pi^0\\nu$, $\\tau^-\\to a_1(1260)^0\\pi^-\\nu$, and $\\tau^-\\to h_1(1170)\\pi^-\\nu$ turn out to be of order ${\\cal O}(10^{-3})$, the channel $\\tau^-\\to f_1(1285)\\pi^-\\nu$ of order ${\\cal O}(10^{-4})$, and channels $\\tau^-\\to K_1(1270)^-\\pi^0\\nu$, $\\tau^-\\to K_1(1270)^0\\pi^-\\nu$, $\\tau^-\\to K_1(1400)^-\\pi^0\\nu$, and $\\tau^-\\to K_1(1400)^0\\pi^-\\nu$ of order ${\\cal O}(10^{-6})$. These results indicate that the branching ratios could be measured in experiments.",
