    Abstract:
    We present a measurement of the B0 ↔ B̄0 oscillalion frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in pp̄ collisions at √s = 1.8 TeV. Such correlations are expected to arise from b quark hudronization and from B** decays. We partially reconstruct B mesons using the semileptonic decays B0 → D(*)-X and B+ rarr; -D̄0X. From the oscillation frequency, we obtain the mass difference between the two B0 mass eigenstates. Δmd = 0.471 -0.068+0.078(stat) ± 0.034(syst)ℏ ps-1, and measure the efficiency and purity of this flavor tagging method for both charged and neutral B mesons.
