A possible simultaneous fit to the available $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$ cross section data nearby $\psi (4660)$ by means of a strong correction to the Coulomb enhancement factor

There are two available set of data on the $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$ cross section above threshold. The BELLE measurement, with ISR return, is compatible with the presen…
