abstract = "We discuss the influence of various contributions of the ΛcΛ¯c potential on the energy dependence of the cross section e+e-→ΛcΛ¯c near the threshold. New BESIII experimental data on the cross section and electromagnetic form factors GE and GM are taken into account. Our predictions are in good agreement with experimental data. We predict a bound state of ΛcΛ¯c at energy ∼38 MeV below the threshold that may manifest itself in anomalous behavior of light meson production cross sections in a given energy region.",
