Abstract
We measure the branching ratios of the Cabibbo-suppressed decays Lambda(+)(c)->Lambda K+ and Lambda(+)(c)->Sigma K-0(+) relative to the Cabibbo-favored decay modes Lambda(+)(c)->Lambda pi(+) and Lambda(+)(c)->Sigma(0)pi(+) to be 0.044 +/- 0.004 (stat.)+/- 0.003 (syst.) and 0.038 +/- 0.005 (stat.)+/- 0.003 (syst.), respectively. We set an upper limit on the branching ratio at the 90% confidence level for Lambda(+)(c)->Lambda K+pi(+)pi(-) of 4.1x10(-2) relative to Lambda(+)(c)->Lambda pi(+), and for Lambda(+)(c)->Sigma K-0(+)pi(+)pi(-) of 2.0x10(-2) relative to Lambda(+)(c)->Sigma(0)pi(+). We also measure the branching fraction for the Cabibbo-favored mode Lambda(+)(c)->Sigma(0)pi(+) relative to Lambda(+)(c)->Lambda pi(+) to be 0.977 +/- 0.015 (stat.)+/- 0.051 (syst.). This analysis was performed using a data sample with an integrated luminosity of 125 fb(-1) collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC.
