Abstract
New measurements of the lifetime and mass of the Csi(c)+ are presented. The Csi(c)+ has been reconstructed through the two decay channels Csi−pi+pi+ and Sigma+K−pi+. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime is measured to be 0.34(+0.07)(-0.05) +/-0.02 ps while the mass is measured to be 2465.8±1.9(stat.)±2.5(syst.) MeV/c2
