Abstract
We present a study of decays to the -odd final state with and . Using collision data with an integrated luminosity of collected by the CDF II detector at the Tevatron we measure a lifetime of . This is the first measurement of the lifetime in a decay to a eigenstate and corresponds in the standard model to the lifetime of the heavy eigenstate. We also measure the product of branching fractions of and relative to the product of branching fractions of and to be , which is the most precise determination of this quantity to date.
