Measurement of the ${\mathrm{\Lambda }}_{\mathit{c}}^{+}$ lifetime

A precise measurement of the ${\mathrm{\Lambda }}_{\mathit{c}}^{+}$ lifetime using approximately 1340 fully reconstructed ${\mathrm{\Lambda }}_{\mathit{c}}^{+}$→${\mathit{pK}}^{\mathrm{-}}$${\mathrm{\pi }}^{+}$ and charge conjugate decays is presented. The data were accumulated by the Fermilab high energy photoproduction experiment E687. The lifetime of the ${\mathrm{\Lambda }}_{\mathit{c}}^{+}$ is measured to be 0.215±0.016±0.008 ps.
