Theoretical interpretation of the $Ξ (1620)$ and $Ξ (1690)$ resonances seen in $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ decay

Hai-Peng Li, Gong-Jie Zhang, Wei-Hong Liang +1

We study the Belle reaction $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ looking at the mass distribution of $π^{+} Ξ$ , where clear signals for the $Ξ (1620)$ and $Ξ (1690)$ resonances are seen. These two…

The $B ˉ_{s}^{0} \to J / ψ π^{0} η$ decay and the $a_{0} (980) - f_{0} (980)$ mixing

Jia-Ting Li, Jia-Xin Lin, Gong-Jie Zhang +2

We study the $B ˉ_{s}^{0} \to J / ψ f_{0} (980)$ and $B ˉ_{s}^{0} \to J / ψ a_{0} (980)$ reactions, and pay attention to the different sources of isospin violation and mixing of $f_{0} (980)$ and $…
