Abstract
This paper reports a study of B meson oscillations using hadronic Z(0) decays with two identified leptons, and updates a previous publicatio n by including data collected in 1994. Decay times are reconstructed f or each of the semileptonic B decays by forming vertices which include the lepton and by estimating the B meson momentum. The mass differenc e, Delta m(d), between the two mass eigenstates in the B-d(0) system i s measured to be 0.430 +/- 0.043 (+0.028)(-0.030) ps(-1), where the fi rst error is statistical and the second error is systematic. For the B -s(0) system, a lower limit of Delta m(s) > 2.2 ps(-1) is obtained at 95% C.L.
