From the analysis of the full Run 1 data set (integrated luminosity of collected during 1992-1996) the exclusive signals from and yield

The first error is the statistical error and the second error is the
systematic error.

From the analysis of partially reconstructed
decays, there is a published result from the analysis of Run 1a data

The analysis of the full Run 1 data set (integrated luminosity of
collected during 1992-1996) yields:

This result has been published: The CDF Collaboration,

The combination of the above two results using exclusive and partially
reconstructed *B* decays yields

The error is the sum of statistical and systematic errors, where the correlated systematic errors are taken into account.

From the analysis of the full Run 1 data set (),
the exclusive signal yields:
(signal = ).

From the analysis of the partially reconstructed decay mode
, with
using the full Run 1 data set (), we have a result using four decay modes,
(signal ).

No combination of the lifetime from the exclusive mode and partially reconstructed mode has been made. Using the average CDF lifetime and the lifetime from semileptonic decays, we determined the CDF average lifetime ratio to be The error is the sum of statistical and systematic errors, where the correlated systematic errors are taken into account.
