Frabetti, P. L.

New measurements of the lifetime and mass of the Ξ c + are presented. The Ξ c + has been reconstructed through the two decay channels Ξ– π + π + and Σ + K – π + . The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime is measured to be 0.34 +0.07 –0.05 (stat.)±0.02 (syst.) ps while the mass is measured to be 2465.8±1.9 (stat.)±2.5 (syst.) MeV/c 2 .
