Description
We have observed six unambiguous decays of the charmed strange baryon Ξc+ (or charge conjugate Ξc-) in the collision of 230 GeV/c negative pions or kaons on a copper target at the CERN SPS using silicon microstrip detectors and charge-coupled devices for vertex reconstruction. Three of them have been reconstructed through the decay chain Ξc+→Ξ-π+π+, Ξ-→Λ0π-, Λ0→pπ- and the other three through the decay chain Ξc+→Σ+K-π+, Σ+→pπ0. We present our measurements of the mass, lifetime and production cross-section of the Ξc+, as well as of the branching ratio for the two decay modes. (orig.)
