Measurement of the B- and B−0 meson lifetimes using semileptonic decays

Published

Journal Article

The lifetimes of the B- and B−0 mesons are measured using the partially reconstructed semileptonic decays B−→D1-v−X, where D is either a D0 or D*+ meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992-1993 and correspond to 19.3 pb−1 of p−p collisions at s = 1.8 TeV. We measure the decay length distributions and find the lifetimes to be τ(B−) = 1.56±0.13±0.06 ps and τ(B−0) = 1.54±0.08±0.06 ps, and the ratio of lifetimes to be τ(B−)/τ(B−0) = 1.01±0.11±0.02, where the first uncertainties are statistical and the second are systematic. © 1996 The American Physical Society.
