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…

Electromagnetic form factors of singly charmed baryons $Σ_{c}$ and $Λ_{c}$ in a covariant quark-diquark model

Ye Cao, Cheng Chen, Dongyan Fu +1

We present a systematic study of the spacelike electromagnetic form factors of the ground-state singly charmed baryons, $Σ_{c}$ ( $Σ_{c}^{++}, Σ_{c}^{+}, Σ_{c}^{0}$ ) and $Λ_{c}^{+}$ , within a covaria…
