1  AAIJ 2020X reports $2964.88$ $\pm0.26$ $\pm0.14$ $\pm0.14$ MeV where the last uncertainty is due to the ${{\mathit \Lambda}_{{c}}^{+}}$ mass. Further studies are required to establish whether the narrow resonance at 2965 MeV is a different baryon from the narrow resonance at 2970 MeV seen by YELTON 2016 .
