摘要：

We have observed two new decay modes of the charmed baryon Xi(c)(+) into Sigma(+)K(-) pi(+) and Sigma(+)K*(0) using data collected with the CLEO II detector, We also present the first measurement of the branching fraction for the previously observed decay mode Xi(c)(+) --> Lambda K- pi(+)pi(+). The branching fractions for these three modes relative to Xi(c)(+) --> Xi(-) pi(+)pi(+) are measured to be 1.18 +/- 0.26 +/- 0.17, 0.92 +/- 0.27 +/- 0.14, and 0.58 +/- 0.16 +/- 0.07, respectively.
