Abstract
The lifetimes of the B- and (B) over bar(0) mesons an measured using t he 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 co llected by the CDF detector at the Fermilab Tevatron collider during 1 992-1995 and correspond to about 110 pb(-1) of (p) over bar p collisio ns at root s = 1.8 TeV. We measure decay lengths and extract the lifet imes to be tau(B-) = 1.637 +/- 0.058(-0.043)(+0.045) ps and tau((B) ov er bar(0)) = 1.474 +/- 0.039(-0.051)(+0.052) ps, and the ratio of the lifetimes to be tau(B-)/tau((B) over bar(0)) = 1.110 +/- 0.056(+0.030) (+0.033), where the first uncertainties are statistical and the second are systematic.
