Measurements of the B- and B-bar0 meson lifetimes using semileptonic decays. Academic Article uri icon

abstract

  • The lifetimes of the B- and B0 mesons are measured using the partially reconstructed semileptonic decays BD1-vX, 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 pb1 of pp collisions at s = 1.8 TeV. We measure the decay length distributions and find the lifetimes to be (B) = 1.560.130.06 ps and (B0) = 1.540.080.06 ps, and the ratio of lifetimes to be (B)/(B0) = 1.010.110.02, where the first uncertainties are statistical and the second are systematic. 1996 The American Physical Society.
