Description

We have measured the charged kaon lifetime using a sample of 15 x 106 tagged kaon decays. Charged kaons were produced in pairs at the DAΦNE φ-factory, e+e- → φ → 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 τ = (12.347±0.030) ns
