$\tau$ decay into a pseudoscalar and an axial-vector meson

L. R. Dai, L. Roca, E. Oset

We study theoretically the decay ${\tau }^{-}\to {\nu }_{\tau }{P}^{-}A$, with $P^{-}$ a ${\pi }^{-}$ or $K^{-}$ and $A$ an axial-vector resonance $b_1(1235)$, $h_1(1170)$, $h_1(1380)$, $a_1(1260)$, $f_1(1285)$ o…
