We have measured branching ratios for three Λc decay modes that have a Σ+ in the final state. Two of the observed decay modes, Λc→Σ+π0 and Λc+→Σ+ω, have no external W-emission amplitudes. Their branching ratios relative to the pK-π+ mode are 0.20±0.03±0.03 and 0.54±0.13±0.06, respectively. We have also significantly improved the measurement of the branching ratio for the previously observed decay mode Λc+→Σ+π+π-. We find its branching ratio relative to pK-π+ to be 0.74±0.07±0.09.
