摘要：

Using the CLEO II detector operating at the e(+)e(-) Cornell Electron Storage Ring (CESR), we present evidence for new decay modes of the Xi(c)(+) into Xi(0) pi+, Xi(0) pi(+)pi(0), and Xi(0) pi(+)pi(-)pi(+). The branching ratios of these decay modes, relative to Xi(c)(+) --> Xi(-)pi(+)pi(+) have been measured to be 0.55 +/- 0.13 +/- 0.09, 2.34 +/- 0.57 +/- 0.37, and 1.74 +/- 0.42 +/- 0.27, respectively.
