Measurement of the decays Λc → Σππ at Belle

Journal Article (Journal Article)

We report measurements of the branching fractions of the decays Λc+→Σ+π-π+, Λc+→Σ0π+π0 and Λc+→Σ+π0π0 relative to the reference channel Λc+→pK-π+. The analysis is based on the full data sample collected at and near the (4S) resonance by the Belle detector at the KEKB asymmetric-energy e+e- collider, corresponding to an integrated luminosity of 711 fb-1. We measure B(Λc+→Σ+π-π+)/B(Λc+→pK-π+)=0.719±0.003±0.024, B(Λc+→Σ0π+π0)/B(Λc+→pK-π+)=0.575±0.005±0.036 and B(Λc+→Σ+π0π0)/B(Λc+→pK-π+)=0.247±0.006±0.019. The listed uncertainties are statistical and systematic, respectively.
