Revealing dipion correlations for the observed substructure near the $π^{+} π^{-}$ mass threshold in $ψ (3686) \to J / ψ π^{+} π^{-}$

Zhong-Yu Wang, Zhe Liu, Xiang Liu

Based on the world's largest $ψ (3686)$ data sample, the BESIII Collaboration recently reported a substructure near the $π^{+} π^{-}$ mass threshold in the decay $ψ (3686) \to J / ψ π^{+} π^{-}$ ,…

Possible molecules of triple-heavy pentaquarks within the extended local hidden gauge formalism

Zhong-Yu Wang, Chu-Wen Xiao, Zhi-Feng Sun +1

In this study, we explore the interactions between mesons and baryons in the open heavy sectors to identify potential triple-heavy molecular pentaquarks. We derive the meson-baryon…

Molecular-type $QQ ss s ˉ$ pentaquarks predicted by an extended hidden gauge symmetry approach

Zhong-Yu Wang, Chu-Wen Xiao, Zhi-Feng Sun +1

In this work, we investigate the double-heavy molecular pentaquark states with the quark contents $ccss s ˉ$ , $bb ss s ˉ$ , and $b css s ˉ$ by using the coupled channel appro…
