Abstract
We report a measurement of the lifetime in the semileptonic decay channel (and its charge conjugate), using approximately of data collected with the D0 detector during 2002–2004. Using 5176 reconstructed signal events, we have measured the lifetime to be . This is the most precise measurement of the lifetime to date.
