Measurement of the B0 - B-0 oscillation frequency using π-B meson charge-flavor correlations in pp collisions at √ s = 1.8 TeV Academic Article uri icon

abstract

  • We present a measurement of the B0 ↔ B-0 oscillation frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in pp collisions at √ s = 1.8 TeV. Such correlations are expected to arise from b quark hadronization and from B** decays. We partially reconstruct B mesons using the semileptonic decays B0 → l+D(*)-X and B+ → l+D-0X. From the oscillation frequency, we obtain the mass difference between the two B0 mass eigenstates, Δmd = 0.471+0.078-0.068(stat) ± 0.034(syst) ħps-1, and measure the efficiency and purity of this flavor tagging method for both charged and neutral B mesons. © 1998 The American Physical Society.
