Abstract: We report measurements of the branching fractions of the decays Λc+Σ+ππ+, Λc+Σ0π+π0 and Λc+Σ+π0π0 relative to the reference channel Λc+pKπ+. The analysis is based on the full data sample collected at and near the ϒ(4S) resonance by the Belle detector at the KEKB asymmetric-energy e+e collider, corresponding to an integrated luminosity of 711 fb1. We measure B(Λc+Σ+ππ+)/B(Λc+pKπ+)=0.719±0.003±0.024, B(Λc+Σ0π+π0)/B(Λc+pKπ+)=0.575±0.005±0.036 and B(Λc+Σ+π0π0)/B(Λc+pKπ+)=0.247±0.006±0.019. The listed uncertainties are statistical and systematic, respectively.
