Electromagnetic form factors of hyperons in the timelike region: A short review

Ling-Yun Dai, Johann Haidenbauer, Ulf-G. Meißner

We review recent experimental and theoretical results for the electromagnetic form factors of hyperons (Y) in the timelike region, accessible in the reactions $e^{+} e^{-} \to Y ˉ Y$ .…

On the quantum numbers of the $X (1880)$

Qin-He Yang, Ling-Yun Dai, Ulf-G. Meißner

We study the properties of the $X (1880)$ , the structure around the $p ˉ p$ threshold that appears in the $3 (π^{+} π^{-})$ invariant mass spectrum in the decay process of $J/ψ\to γ3(π…

Study of the electromagnetic form factors of the nucleons in the timelike region

Qin-He Yang, Di Guo, Ming-Yan Li +3

The electromagnetic form factors $G_{E}$ and $G_{M}$ of the proton and neutron in the timelike region are extracted in a study of the processes $e^{+} e^{-} \to p ˉ p$ and $e…

Study of the timelike electromagnetic form factors of the $Λ_{c}$

Di Guo, Qin-He Yang, Ling-Yun Dai

In this paper, the reaction of electron-positron annihilation into $Λ_{c}^{+} Λ ˉ_{c}^{-}$ is investigated. The $Λ_{c}^{+} Λ ˉ_{c}^{-}$ scattering amplitudes are obtained by solving the Lippmann…

Study of electron-positron annihilation into $K K ˉ π$ within resonance chiral theory

Bing-Hai Qin, Wen Qin, Ling-Yun Dai

In this paper, a coherent study of the $e^{+} e^{-}$ annihilation into $K^{+} K^{-} π^{0}$ , $K_{S}^{0} K_{L}^{0} π^{0}$ and $K_{S}^{0} K^{\pm} π^{\mp}$ is carried out within the framework of resonance chiral theory.…
