A new measurement of the ξc+ lifetime
A precise determination of the charm-strange baryon Ξc+ lifetime is presented. The data were accumulated by the Fermilab high-energy photoproduction experiment FOCUS. The measurement is made with 300Ξc+ → Ξ-π+π+ decays, 130Ξc+ → Σ+K-π+decays, 45Ξc+ → pK-π+ decays and 58Ξc+ → Λ0K-π+π+ decays. The Ξc+ lifetime is measured to be 0.439 ± 0.022 ± 0.009 ps. © 2001 Elsevier Science B.V. All rights reserved.
