Electromagnetic form factors of singly charmed baryons $I^£_{c}$ and $I^_{c}$ 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, $I^£_{c}$ ( $I^£_{c}^{++}, I^£_{c}^{+}, I^£_{c}^{0}$ ) and $I^_{c}^{+}$ , within a co…

Role of $K_{0}^{*} (700)$ exchange in the $p p ˉ \to I^ I^ˉ $ reaction

Hao-Nan Wang, Cheng Chen, Xing-Yi Ji +4

The paper uses an effective Lagrangian model to study the antiproton‑proton → Λ Λ̄ reaction, showing that t‑channel exchange of the scalar meson K*_0(700) together with s‑channel v…

Investigation of the baryon time-like electromagnetic form factors in the electron-positron annihilation reactions

Ju-Jun Xie, Cheng Chen

Based on the experimental measurements of the electron-positron annihilation reactions into a baryon ( $B$ ) and anti-baryon ( $B ˉ$ ) pair, the electromagnetic form factors of hyp…
