Discerning the two $K_{1} (1270)$ poles in $D^{0} \to π^{+} V P$ decay

G. Y. Wang, L. Roca, E. Oset

Within the chiral unitary approach, the axial-vector resonance $K_{1} (1270)$ has been predicted to manifest a two-pole nature. The lowest pole has a mass of 1195 Mev and a width of 2…

$τ$ decay into a pseudoscalar and an axial-vector meson

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

We study theoretically the decay $τ^{-} \to ν_{τ} P^{-} A$ , with $P^{-}$ a $π^{-}$ or $K^{-}$ and $A$ an axial-vector resonance $b_{1} (1235)$ , $h_{1} (1170)$ , $h_{1} (1380)$ , $a_{1} (1260)$ , $f_{1} (1285)$ o…

Radiative decay into $γ P$ of the low lying axial-vector mesons

H. Nagahiro, L. Roca, E. Oset

We evaluate the radiative decay into a pseudoscalar meson and a photon of the whole set of the axial-vector mesons dynamically generated from the vector-pseudoscalar meson ( $V P$ ) i…

Clues for the existence of two $K_{1} (1270)$ resonances

L. S. Geng, E. Oset, L. Roca +1

The axial vector meson $K_{1} (1270)$ was studied within the chiral unitary approach, where it was shown that it has a two-pole structure. We reanalyze the high-statistics WA3 experim…
