$a_{0} (980)$ production, triangle singularity, and non- $ϕ$ background in the $J / ψ \to ϕ η π^{0}$ reaction

Hai-Peng Li, Wei-Hong Liang, Chu-Wen Xiao +1

We study the $J / ψ \to ϕ η π^{0}$ reaction measured recently by the BESIII collaboration with high precision, paying attention to three important aspects: 1) The production of the $a_0(…

The $D_{s 0}^{} (2317)^{+}$ decay to $D_{s}^{+} π^{0}$ and $D_{s}^{+} γ$

Pei-Sen Su, Wen-Tao Lyu, Wei-Hong Liang +1

We study the strong decay of $D_{s 0}^{*} (2317)^{+}$ to $D_{s}^{+} π^{0}$ considering the coupled channels of $D^{0} K^{+}, D^{+} K^{0}, D_{s}^{+} η$ and $D_{s}^{+} π^{0}$ within a picture for the interaction…

Superexotic $K^{+} D^{+} K^{*+}$ bound state

Wen-Hao Jia, Pei-Shen Su, Wei-Hong Liang +2

We study a system made from $K^{*+} D^{*+} K^{*+}$ with charge $3$ , isospin $I = 3/2$ , spin $J = 3$ , and a quark content of $c d ˉ s ˉ u s ˉ u$ , which make it highly exotic relat…

The $Λ_{c}^{+} \to Λ π^{+} π^{+} π^{-}$ reaction, and a triangle singularity producing the $Σ^{*} (1430)$ state

Yi-Yao Li, Jing Song, Eulogio Oset +2

We study the decay $Λ_{c}^{+} \to Λ π^{+} π^{+} π^{-}$ , focusing on the production of the $Σ^{*} (1430)$ resonance observed by the Belle Collaboration. Interpreted as a dynamically generated sta…
