   Abstract:
   The lifetime of the [Formula Presented] meson is measured using the semileptonic decay [Formula Presented] The data sample consists of about [Formula Presented] of [Formula Presented] collisions at [Formula Presented] collected by the CDF detector at Fermilab. Four different [Formula Presented] decay modes are reconstructed resulting in approximately 600 [Formula Presented] signal events. The [Formula Presented] meson lifetime is determined to be [Formula Presented] where the first and second uncertainties are statistical and systematic, respectively. The [Formula Presented] meson decay length distribution is examined for a lifetime difference [Formula Presented] between the two mass eigenstates of the [Formula Presented] meson. An upper limit of ΔΓ/Γ<0.83 is set at the 95% confidence level. © 1999 The American Physical Society.
