Description/AbstractThe lifetimes of the B{sup {minus}} and {bar B}{sup 0} mesons are measured using the partially reconstructed semileptonic decays {bar B}{r_arrow}Dl{sup {minus}}{bar {nu}}X, where D is either a D{sup 0} or D{sup {asterisk}+} meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992{endash}1995 and correspond to about 110thinsppb{sup {minus}1} of {bar p}p collisions at {radical} (s) =1.8thinspTeV. We measure decay lengths and extract the lifetimes to be {tau}(B{sup {minus}})=1.637{plus_minus}0.058{sub {minus}0.043}{sup +0.045} ps and {tau}({bar B}{sup 0})=1.474{plus_minus}0.039{sub {minus}0.051}{sup +0.052}thinspps, and the ratio of the lifetimes to be {tau}(B{sup {minus}})/{tau}({bar B}{sup 0})=1.110{plus_minus}0.056{sub {minus}0.030}{sup +0.033}, where the first uncertainties are statistical and the second are systematic. {copyright} {ital 1998} {ital The American Physical Society}
