Abstract
We present a measurement of the meson lifetime in the decay mode using the Collider Detector at Fermilab II detector at the Fermilab Tevatron Collider. From a sample of about of collisions at , we reconstruct pairs with invariant mass in the kinematically allowed range . A fit to the decay-length distribution of 238 signal events yields a measured meson lifetime of .
