description

Abstract We have observed six unambiguous decays of the charmed strange baryon Ξc+ (or charge conjugate Ξc−) in the 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+ →pπ0. We present our measurements of the mass, lifetime and production cross-section of the Ξc+, as well as of the branching ration for the two decay modes.
