abstract

  • We have observed the previously unseen decay modes Λπ+π0, Σ0π+π0 and Σ0π-π+π+ of the charmed baryon Λc+, as well as Λc+→Σ0π+ observed previously by ARGUS. The branching ratios for these four decay modes relative to Λc+→pK-π+ are measured to be 0.73 ±0.09± 0.16, 0.36 ±0.09±0.10, 0.21±0.05±0.05, and 0.21±0.02 ±0.04, respectively. Using the recent CLEO measurement of the branching ratio for Λc+→pK- π+, these modes account for 6% of Λc+ decays. © 1994.
