Exploring charmonia $η_{c} (6 S, 7 S)$ in the $Λ_{c}^{+} Λ ˉ_{c}^{-}$ invariant mass spectrum of $B^{0} \to K_{S}^{0} Λ_{c}^{+} Λ ˉ_{c}^{-}$

Cheng-Xi Liu, Jun-Zhang Wang, Xiang Liu

We analyze the $B^{0} \to K_{S}^{0} Λ_{c}^{+} Λ ˉ_{c}^{-}$ decay recently observed by the LHCb Collaboration. The $Λ_{c}^{+} Λ ˉ_{c}^{-}$ invariant-mass spectrum exhibits an accumulation near 4.63~Ge…

Understanding the enhanced $ϕ η^{'}$ decay mode of the $ϕ (2170)$ through strange-meson loops

Qin-Song Zhou, Jun-Zhang Wang, Dan Guo

The nature of the strangeonium-like $ϕ (2170)$ remains controversial. Recent measurements of $e^{+} e^{-} \to ϕ η^{(')}$ reveal a striking puzzle: a broad $ϕ (2170)$ -like structure appe…
