Phys. Rev. Lett. 62, 1240–1242 (1989)Σc++ and Σc0 production from e+e- annihilation in the Υ energy regionReceived 13 December 1988; published in the issue dated 13 March 1989 We have observed Σc++ and Σc0 baryons in nonresonant e+e- interactions through their decays to Λc+π± using the CLEO detector. The mass difference M(Σc++)-M(Λc+) is measured to be 167.8±0.4±0.3 MeV; for M(Σc0)-M(Λc+) we find 167.9±0.5±0.3 MeV. Σc decay accounts for (18±3±5)% of Λc+ production. © 1989 The American Physical Society URL:
