$P_{c} (4440)$ 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…

Roles of $f_{0} (500)$ and $f_{0} (980)$ in the $D_{(s)}^{+} \to π^{+} π^{+} π^{-}$ decays

Zhong-Yu Wang, Wei Liang

With the recent measurements of the $D_{s}^{+} \to π^{+} π^{+} π^{-}$ and $D^{+} \to π^{+} π^{+} π^{-}$ decays by the LHCb Collaboration, we study these two decay process…

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…

Determination of the $K^{+} K ˉ^{0}$ scattering length and effective range and its relation to the $a_{0}^{+} (980)$ from the $χ_{c 1} \to π^{+} π^{-} η$ reaction

Hai-Peng Li, Jia-Xin Lin, Wei-Hong Liang +1

We analyze the clean cusp, seen in the $η π$ mass distribution with high precision of the $χ_{c 1} \to η π^{+} π^{-}$ reaction in the BESIII experiment, with the aim of making a precise d…

How to unravel the nature of the $Σ^{*} (1430) (1/ 2^{-})$ state from correlation functions

Hai-Peng Li, Chu-Wen Xiao, Wei-Hong Liang +3

We calculate the correlation functions for the $K ˉ^{0} p, π^{+} Σ^{0}, π^{0} Σ^{+}, π^{+} Λ$ , and $η Σ^{+}$ states, which in the chiral unitary approach predict an excited $Σ^{*} (1/ 2^{-})$ state…
