Dynamical origin of universal two-pole structures and their light quark mass evolution

Jia-Ming Xie, Jun-Xu Lu, Li-Sheng Geng +1

Two-pole structures refer to the fact that two dynamically generated states are located close to each other between two coupled channels and have a mass difference smaller than the…

Systematic studies of $D D K K$ and $D D ˉ K K ˉ$ four-hadron molecules

Ya-Wen Pan, Ming-Zhu Liu, Jun-Xu Lu +1

Assuming that $D_{s 0}^{*} (2317)$ is a $D K$ molecular state with a binding energy of 45 MeV, we investigate the existence of four-hadron molecules, $D D K K$ and $D\Bar{D}K\Bar{K}$, wi…

Productions of $D_{s 0}^{*} (2317)$ and $D_{s 1} (2460)$ in $B_{(s)}$ and $Λ_{b} (Ξ_{b})$ decays

Ming-Zhu Liu, Xi-Zhe Ling, Li-Sheng Geng

Recent studies show that $D_{s 0}^{*} (2317)$ and $D_{s 1} (2460)$ contain large molecular components. In this work, we employ the naive factorization approach to calculate the prod…

Long-range $S$ -wave $D D^{*}$ interaction in covariant chiral effective field theory

Qing-Yu Zhai, Ming-Zhu Liu, Jun-Xu Lu +1

Motivated by the recent lattice QCD study of the $D D^{*}$ interaction at unphysical quark masses, we perform a theoretical study of the $D D^{*}$ interaction in covariant chiral effecti…

Production of the $Ξ N$ dibaryon as a weakly bound system in $pp$ collisions

Tian-Chen Wu, Atsushi Hosaka, Li-Sheng Geng

The $Ξ N$ interaction plays an important role in our understanding on the long-anticipated $H$ -dibaryon. Recent lattice QCD calculations verified the attractive nature of the $Ξ N$ i…

Production rates of hidden-charm pentaquark molecules in $Λ_{b}$ decays

Ya-Wen Pan, Ming-Zhu Liu, Li-Sheng Geng

The partial decay widths and production mechanism of the three pentaquark states, $P_{ψ}^{N} (4312)$ , $P_{ψ}^{N} (4440)$ , and $P_{ψ}^{N} (4457)$ , discovered by the LHCb Collaboration in 201…

Productions of $X (3872)$ , $Z_{c} (3900)$ , $X_{2} (4013)$ , and $Z_{c} (4020)$ in $B_{(s)}$ decays offer strong clues on their molecular nature

Qi Wu, Ming-Zhu Liu, Li-Sheng Geng

The exotic states $X (3872)$ and $Z_{c} (3900)$ have long been conjectured as isoscalar and isovector $D ˉ^{*} D$ molecules. In this work, we first propose the triangle diagram mechan…
