Study of the $e^{+} e^{-} \to ϕ K^{+} K^{-}$ reaction within triangle dynamics and its implications for the $ϕ (2170)$

Xiang Wei, Cheng Chen, Si-Wei Liu +4

We revisit the $e^{+} e^{-} \to ϕ π^{+} π^{-}$ reaction within the $K_{1}$ - $K ˉ$ - $K$ triangle dynamics framework, in which the $e^{+} e^{-}$ pair annihilates through one-photon exchange approxim…

Unveiling the elusive $Σ (1380)$ resonance through coupled-channel dynamics in $Λ_{c}^{+} \to η π^{+} Λ$ reaction

Wen-Tao Lyu, Si-Wei Liu, Jia-Jun Wu +2

We investigate the $Λ_{c}^{+} \to η π^{+} Λ$ decay measured by the Belle and BESIII Collaborations, focusing on the possible role of the $Σ (1380)$ state with spin-parity $J^{P} = 1/ 2^{-}$ . In o…

Role of $Σ (1660)$ in the $K^{-} p \to π^{0} π^{0} Σ^{0}$ reaction

Xing-Yi Ji, Si-Wei Liu, Wen-Tao Lyu +3

The processes of $K^{-} p \to π^{0} π^{0} Σ^{0}$ and $K^{-} p \to π^{0} Λ (1405)$ are studied within the effective Lagrangian approach. In addition to the ``background" contribution from the $u$ …
