摘要：
Another decay mode of the LAMBDA(b)0 (open-beauty baryon) state has been observed: LAMBDA(b)0 --> LAMBDA(c)+ pi+ pi- pi-. In addition, new results on the previously observed decay channel LAMBDA(b)0 --> pD0 pi-, are reported. These results confirm our previous findings on LAMBDA(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>>.
