In search for signals of the $D D ˉ$ bound state $X (3700)$ from study of the $B^{+} \to D^{+} D^{-} K^{+}$ , $B^{0} \to D^{+} D^{-} K^{0}$ and $Λ_{b} \to D^{+} D^{-} Λ$ reactions

Xiu-Lei Ren, Hai-Peng Li, Wei-Hong Liang +2

We perform a theoretical study of the $B^{+} \to D^{+} D^{-} K^{+}$ , $B^{0} \to D^{+} D^{-} K^{0}$ and $Λ_{b} \to D^{+} D^{-} Λ$ reactions by looking at the production mechanisms, with special emphasis…

Correlation function and bound state from the $K D_{s 0}^{*} (2317)$ interaction

Wen-Hao Jia, Hai-Peng Li, Wei-Hong Liang +2

In anticipation of the new wave of ALICE experiments on particle-resonance correlation functions, we study the interaction of a kaon with the $D_{s 0}^{*} (2317)$ resonance. Assuming t…

Study of the $J / ψ \to Λ Σ ˉ^{0} η$ reaction

L. R. Dai, Wen-Tao Lyu, E. Oset

We study the isospin violating $J / ψ \to Λ Σ ˉ^{0} η$ reaction, recently measured by the BESIII collaboration, by looking at the dominant terms with $Σ ˉ^{0}$ and a pair of pseudosc…

Searching for a $P_{cs} (4200)$ state in the $Λ_{b} \to ϕ η_{c} Λ$ reaction

Wen-Tao Lyu, Eulogio Oset

We propose the $Λ_{b} \to ϕ η_{c} Λ$ reaction to observe a $P_{cs}$ state around $4200$ MeV, predicted at lower masses than expected from comparison with the $P_{c}$ states, stemming as a c…

$a_{0} (980)$ 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…
