Abstract
We present a measurement of the lifetime in fully and partially reconstructed decays in collected in collisions at by the CDF II detector at the Fermilab Tevatron. We measure . The ratio of this result and the world average lifetime yields , which is in agreement with recent theoretical predictions.
