$P_{c} (4440)$ and $P_{c} (4457)$ decay into $D ˉ Σ_{c}$ and $D ˉ Λ_{c}$ and the spin of the $P_{c}$ states

Zi-Ying Yang, Jing Song, Wei-Hong Liang +1

We address the issue of the width and spin assignment of the $P_{c} (4440)$ and $P_{c} (4457)$ pentaquark states. We calculate the partial decays widths of the particles into $J / ψ N$ , $\b…

The role of the $f_{0} (1710)$ and $a_{0} (1710)$ resonances in the $D^{0} \to ρ^{0} ϕ$ , $ω ϕ$ decays

Natsumi Ikeno, Wen-Hao Jia, Wei-Hong Liang +1

We study the $D^{0} \to ρ^{0} ϕ$ , $ω ϕ$ decays which proceed in a direct mode via internal emission with equal rates. Yet, the experimental branching ratio for the $ρ^{0} ϕ$ mode is twice…

Study of the exotic three-body $N D^{} K ˉ^{}$ system

Qing-Yu Zhai, Raquel Molina, Eulogio Oset +1

We have studied the $N D^{*} K ˉ^{*}$ system in the framework of the Fixed Center Approximation to the Faddeev equations, taking the exotic $D^{*} K ˉ^{*}$ system as the cluster a…

One or two poles for the $Ξ (1820)$ ?

R. Molina, Wei-Hong Liang, Chu-Wen Xiao +2

In this talk, we present a new interpretation for the recently observed $Ξ (1820)$ resonance. We recall that the chiral unitary approach for the interaction of pseudoscalar mesons w…

Determination of the binding and $D K$ probability of the $D_{s 0}^{*} (2317)$ from the $(D ˉ K ˉ)^{-}$ mass distributions in $Λ_{b} \to Λ_{c} (D ˉ K ˉ)^{-}$ decays

Hai-Peng Li, Wei-Hong Liang, Chu-Wen Xiao +2

We study the $Λ_{b} \to Λ_{c} D ˉ^{0} K^{-}$ and $Λ_{b} \to Λ_{c} D^{-} K ˉ^{0}$ decays which proceed via a Cabibbo and $N_{c}$ favored process of external emission, and we determin…

The $Λ_{c}^{+} \to η π^{+} Λ$ reaction and the $Λ a_{0}^{+} (980)$ and $π^{+} Λ (1670)$ contributions

Man-Yu Duan, Wen-Tao Lyu, Chu-Wen Xiao +4

We study from the theoretical point of view the $Λ_{c}^{+} \to π^{+} η Λ$ reaction, recently measured by the Belle and BESIII Collaborations, where clear signals are observed for $a_0(980)…
