Description
Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have observed production of the charmed-strange baryon Ξc+ and its neutral isospin partner, the Ξc0. The Ξc+ was reconstructed in the final state Ξ-π+π+, thile the Ξc0 was seen in decay to Ξ-π+ and Ξ-π+π+π-. The average Ξc fragmentation spectrum has been determined, as well as the production cross section times branching ratio for each decay mode. The charged and neutral masses were measured to be 2465.1±3.6±1.9 MeV/c2 and 2472.1±2.7±1.6 MeV/c2 respectively, corresponding to a mass-splitting, M(Ξc+)-M(Ξc0), of -7.0±4.5±2.2 MeV/c2. (orig.)
