The electromagnetic form factors of ${\Lambda }_c$ hyperon in the vector meson dominance model

Junyao Wan, Yongliang Yang, Zhun Lu

We apply a modified vector meson dominance (VMD) model to analyze the electromagnetic form factors of the ${\Lambda }_c$ hyperon in the time-like reaction $e^+e^-\rightarrow Λ_c^+ \barΛ_c^-…
