The role of triangle singularity in the $B^{0} \to D^{-} π^{+} a_{0} (980) (π^{0} η)$ decay

Wei Wang, Dazhuang He, Xuan Luo

The triangle singularity interpretation of the \replyhe{ $a_{1} (1420)$ } observed by the COMPASS Collaboration has been widely accepted. In this work, we investigate the triangle mecha…

Triangle mechanism in the decay process $J / ψ \to K^{-} K^{+} a_{1} (1260)$

Xuan Luo, Dazhuang He, Yiling Xie +1

The role of triangle mechanism in the decay process $J / ψ \to K^{-} K^{+} a_{1} (1260)$ is probed. In this mechanism, a close-up resonance with mass $1823$ MeV and width $122$ MeV decays in…

Theoretical study in the $B ˉ^{0} \to J / ψ K ˉ^{* 0} K^{0}$ and $B ˉ^{0} \to J / ψ f_{1} (1285)$ decays

DaZhuang He, Xuan Luo, YiLing Xie +1

We study the decay processes of $B ˉ^{0} \to J / ψ K ˉ^{* 0} K^{0}$ and $B ˉ^{0} \to J / ψ f_{1} (1285)$ to analyse the $f_{1} (1285)$ resonance. By the calculation within chiral unitary…
