Measurements of the mass and lifetime of the Ξc+ decaying into Ξ-pi+pi+ are presented. The data were accumulated by the Fermilab high-energy photoproduction experiment E687. The mass of the Ξc+ is measured to be 2464.4±2.0±1.4 MeV/c2 and the lifetime is measured to be 0.41-0.08+0.11±0.02 ps.

Abstract

Measurements of the mass and lifetime of the Ξc+ decaying into Ξ-pi+pi+ are presented. The data were accumulated by the Fermilab high-energy photoproduction experiment E687. The mass of the Ξc+ is measured to be 2464.4±2.0±1.4 MeV/c2 and the lifetime is measured to be 0.41-0.08+0.11±0.02 ps.
