Exploring the $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\Lambda }_c^{-}$ cross sections

Yong Xie, Zhiqing Liu

A simultaneous fit is performed to the $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\Lambda }_c^{-}$ cross section data measured by Belle and BESIII from threshold up to 5.4 GeV. In order to accommodate both the BESIII…
