Pionic and radiative transitions from $T_{c s ˉ 0}^{+} (2900)$ to $D_{s 1}^{+} (2460)$ as a probe of the structure of $D_{s 1}^{+} (2460)$

Zi-Li Yue, Cheng-Jian Xiao, Dian-Yong Chen

In this work, we evaluated the widths of the pionic and radiative transitions from the $T_{c s ˉ 0}^{+} (2900)$ to the $D_{s 1}^{+} (2460)$ in the $D_{s 1}^{+} (2460)$ molecular frame…

The decays of the fully open flavor state $T_{c s ˉ 0}^{0}$ in a $D^{} K^{}$ molecule scenario

Zi-Li Yue, Cheng-Jian Xiao, Dian-Yong Chen

Inspired by the recent observations of $T_{c s ˉ 0}^{0/ ++}$ in the the processes $B^{0} \to D ˉ^{0} D_{s}^{+} π^{-}$ and $B^{+} \to D^{-} D_{s}^{+} π^{+}$ by LHCb Collaboration, we investigate the…

A study of the decays of $S -$ wave $D ˉ^{} K^{}$ hadronic molecules: the scalar $X_{0} (2900)$ and its spin partners $X_{J (J = 1, 2)}$

Cheng-Jian Xiao, Dian-Yong Chen, Yu-Bing Dong +1

In this work, we investigated the decays of the fully open-flavor tetraquark state $X_{0} (2900)$ which was observed by the LHCb Collaboration very recently. Here, the $X_{0} (2900)$ was…

Towards the decay properties of deuteron-like state $d_{N Ω}$

Cheng-Jian Xiao, Yu-Bing Dong, Thomas Gutsche +2

Recent lattice QCD calculations showed that a $d_{N Ω}$ dibaryon state similar to the deuteron with small binding energy may exist. In this work we propose a hadronic molecular appr…

Exploring the molecular scenario of $P_{c} (4312)$ , $P_{c} (4440)$ , and $P_{c} (4457)$

Cheng-Jian Xiao, Yin Huang, Yu-Bing Dong +2

In the present work, we assign the newly observed $P_{c} (4312)$ as a $I (J^{P}) = \frac{1}{2} (\frac{1}{2})^{-}$ molecular state composed of $Σ_{c} D ˉ$ , while $P_{c} (4440)$ and $P_c(4457)…

Strong decays of the $Ξ_{b} (6227)$ as a $Σ_{b} K ˉ$ molecule

Yin Huang, Cheng-jian Xiao, Li-Sheng Geng +1

We study the strong decays of the newly observed $Ξ_{b} (6227)$ assuming that it is a pure $Σ_{b} K ˉ$ molecular state. Considering four possible spin-parity assingments $J^P=1/2^{\p…
