Abstract
We have measured the charged kaon lifetime using a sample of 15 x 10(6) tagged kaon decays. Charged kaons were produced in pairs at the DA Phi NE phi-factory, e(+)e(-) -> phi -> K+K-. The decay of a K+ was tagged by the production of a K- and viceversa. The lifetime was obtained, for both charges, from independent measurements of the decay time and decay length distributions. From fits to the four distributions we find tau = (12.347 +/- 0.030) ns.
