Measurement of the mass and lifetime of the Xi(c)+
by P.L. Frabetti et al.
Abstract. Measurements of the mass and lifetime of the Xi(c)+ decaying into Xi-pi+pi+ are presented. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The mass of the Xi(c)+ is measured to be 2464.4 +- 2.0 +- 1.4 MeV/c^2 and the lifetime is measured to be 0.41(+0.11-0.08) +- 0.02 ps.
