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…

New insights into the doubly charmed exotic mesons

Di Guo, Qin-He Yang, Ling-Yun Dai +1

Using effective Lagrangians constrained by the heavy quark spin symmetry and chiral symmetry, for the light quarks, we analyze the $D^{0} D^{0} π^{+}$ , $D ˉ^{0} D^{0} π^{0}$ and $D^0\bar{D}^{…
