Description
We have investigated the electromagnetic form factors of charmed $\Lambda_c^+$ baryon and the total cross sections of the $𝑒^+𝑒^− \to 𝛬^+_c \bar{\Lambda}_c^-$ reaction within the extended vector meson dominance model. By including the charmonium-like states 𝜓(4500), 𝜓(4660), 𝜓(4790), and the possible 𝜓(4900) state, the current experimental data can be well reproduced.
