1  AAIJ 2020X reports $2938.55$ $\pm0.21$ $\pm0.17$ $\pm0.14$ MeV where the last uncertainty is due to the ${{\mathit \Lambda}_{{c}}^{+}}$ mass. Observes that the broader resonance at 2930 MeV seen in ${{\mathit B}^{-}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \Lambda}_{{c}}^{+}}{{\overline{\mathit \Lambda}}_{{c}}^{-}}$ by LI 2018A and AUBERT 2008H resolves into two narrower peaks at approximately 2939 MeV and 2923 MeV.
