Abstract

We present a study of time dependent B⁰-$$\bar{B}$$⁰ mixing in p$$\bar{p}$$ collisions at 1.8 TeV using 110 pb^-1 collected with the CDF detector at the Fermilab Tevatron Collider. B mesons are partially reconstructed using the semileptonic decays B⁰→l⁺D^*-X and B⁺→l⁺$$\bar{D}$$⁰X (and their charge conjugates). B meson-charged pion correlations are used in order to determine the flavor of the B meson at t=0. Such correlations are expected to arise from pions produced in the fragmentation chain and also from B** decays. We measure the efficiency and purity of this flavor tagging method for both charged and neutral B mesons.

Study of Charged Particle Species Produced in Association with $$\bar{B}$$⁰, B^-, and $$\bar{B}$$$$0\atop{s}$$ Mesons in p$$\bar{p}$$ collisions at √s = 1.96-TeV

Thesis/Dissertation Usynin, Denys

The authors study the yields of charged kaons, charged pions, and protons produced in association with B mesons produced in proton-antiproton collisions at center of mass energy 1960 GeV using 355 pb^-1 of data collected with the CDF detector at the Fermilab Tevatron. This is the first reported measurements of these yields at a hadron collider. The B mesons are reconstructed using their semileptonic decays: B⁰ → ℓ⁺D^-X, D^- → K⁺π^-π^-; B⁰ → ℓ⁺D*^-X, D*^- → π^-$$\bar{D}$$⁰,$$\bar{D}$$⁰ → K⁺π^-; B⁺ → ℓ⁺$$\bar{D}$$⁰X, $$\bar{D}$$⁰ → K⁺π^-; B_s→ℓ⁺D$$-\atop{s}$$ X, D$$-\atop{s}$$ → π^-Φ,Φ → K⁺K^-.

Observation of {pi} - B meson charge-flavor correlations and measurement of time dependent B{sup 0} Bbar{sup 0} mixing in p{bar p} collisions

Conference

We present evidence for charge correlations of {ital B} mesons with charged particles produced in {ital p{anti p}} Collisions at 1.8 TeV. Such correlations are expected to arise from pious produced in the fragmentation chain and from {ital B}{sup **} decays. We measure the efficiency and purity of this flavor tagging method for both charged and neutral {ital B} mesons. We apply these correlations to {ital B} mesons reconstructed in 110 pb{sup -1} of data collected with the CDF detector at the Fermilab Tevatron Collider. {ital B} mesons are either partially reconstructed, using the semileptonic decays {ital B}{sup 0} {yields}more »« less

Measurement of the B{sup 0}B(bar sign){sup 0} oscillation frequency using l{sup -}D{sup *+} pairs and lepton flavor tags

Journal Article Affolder, T; Akimoto, H; Akopian, A; ... - Physical Review. D, Particles Fields

The oscillation frequency {delta}m{sub d} of B{sup 0}B(bar sign){sup 0} mixing is measured using the partially reconstructed semileptonic decay B(bar sign){sup 0}{yields}l{sup -}{nu}(bar sign)D{sup *+}X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb{sup -1} of p(bar sign)p collisions at {radical}(s)=1.8 TeV. We estimate the proper decay time of the B(bar sign){sup 0} meson from the measured decay length and reconstructed momentum of the l{sup -}D{sup *+} system.

Journal Article Blair, R; Byrum, K; Kovacs, E; ... - Physical Review Letters

We present a measurement of the B{sup 0}{leftrightarrow}{bar B}{sup 0} oscillation frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in p{bar p} collisions at {radical}(s)=1.8 TeV. Such correlations are expected to arise from b quark hadronization and from B{sup {asterisk}{asterisk}} decays. We partially reconstruct B mesons using the semileptonic decays B{sup 0}{r_arrow}l{sup +}D{sup ({asterisk}){minus}} X and B{sup +}{r_arrow}l{sup +}{bar D}{sup 0}X. From the oscillation frequency, we obtain the mass difference between the two B{sup 0} mass eigenstates, {Delta}m{sub d}=0.471{sup +0.078}{sub {minus}0.068} (stat){plus_minus}0.034(syst ){h_bar} ps{sup {minus}1}, and measure themore »« less
Measurement of B[sup 0]-[bar B][sup 0] flavor oscillations using jet-charge and lepton flavor tagging in p[bar p] collisions at [radical] (s) =1. 8 TeV

Journal Article Blair, R; Byrum, K; Kovacs, E; ... - Physical Review, D

We present a measurement of the mass difference [Delta]m[sub d] for the B[sup 0] meson and the statistical power of the [ital b] flavor tagging methods used. The measurement uses 90 pb[sup [minus]1] of data from p[bar p] collisions at [radical] (s) =1.8 TeV collected with the CDF detector. An inclusive lepton trigger is used to collect a large sample of [ital B] hadron semileptonic decays. The mass difference [Delta]m[sub d] is determined from the proper time dependence of the fraction of [ital B] hadrons that undergo flavor oscillations. The flavor at decay is inferred from the charge of themore »« less
