Abstract

We report a precise measurement of the D±s meson lifetime. The data were taken by the SELEX experiment (E781) spectrometer using 600 GeV/cΣ−, π− and p beams. The measurement has been done using 918 reconstructed D±s. The lifetime of the D±s is measured to be 472.5±17.2±6.6 fs, using K∗(892)0K± and φπ± decay modes. The lifetime ratio of Ds± to D0 is 1.145±0.049.
