Study of the timelike electromagnetic form factors of the ${\Lambda }_c$

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

In this paper, the reaction of electron-positron annihilation into ${\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$ is investigated. The ${\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$ scattering amplitudes are obtained by solving the Lippmann…
