The Λ 0b beauty baryon production in proton-proton interactions at √S=62 GeV: a second observation

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Another decay mode of the Λ 0b (open-beauty baryon) state has been observed: Λ 0b →Λ +c π+π−π−. In addition, new results on the previously observed decay channel, Λ 0b →pD0π−, are reported. These results confirm our previous findings on Λ 0b 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».
