Summary Another decay mode of the Λ b 0 (open-beauty baryon) state has been observed: Λ b 0 →Λ c + π+π−π−. In addition, new results on the previously observed decay channel, Λ b 0 →pD0π−, are reported. These results confirm our previous findings on Λ b 0 production at the ISR. The mass value (5.6 GeV/c2) is found to be in good agreement with theoretical predictions. The production mechanism is found to be «leading».
