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

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

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

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

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

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

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…
