Abstract
The lifetimes of the B- and (B) over bar(0) mesons are measured using the partially reconstructed semileptonic decays (B) over bar --> Dl(-) <(nu)over bar>X, where D is either a D-0 or D(+) meson. The data were collected by the CDF detector at the Fermilab Tevatron collider durin g 1992-1993 and correspond to 19.3 pb(-1) of <(p)over bar p> collision s at root s = 1.8 TeV. We measure the decay length distributions and f ind the lifetimes to be tau(B-)= 1.56 +/- 0.13 +/- 0.06 ps and tau(($) over bar(0)) = 1.54 +/- 0.08 +/- 0.06 ps, and the ratio of lifetimes to be tau(B-)/tau((B) over bar(0)) = 1.01 +/- 0.11 +/- 0.02, where the first uncertainties are statistical and the second are systematic.
