Book excerpt: Recent results on b quark and B meson production cross sections have been obtained at √s = 1.8 TeV proton-antiproton collisions using the Collider Detector Facility (CDF) at Fermilab, using the exclusive decay modes B{sup {+-}} →J/[Psi] K{sup {+-}} and B° → J/[Psi] K*.

Book excerpt: Abstract: The measurement of heavy quark cross-sections provides important tests of the QCD theory. This paper reviews recent measurements of single b-quark and correlated b-quark cross-sections at CDF. Two new measurements of the single b-quark production at CDF agree with the first result from CDF Run II. This clarifies the experimental situation and confirms the recent agreement of theoretical prediction with data. A new measurement of the correlated b{bar b} cross-section with dimuon events at CDF is presented. It agrees with theory and it does not confirm the anomalously large b{bar b} cross-section seen in Run I by CDF and D0 in dimuon events.

Book excerpt: Preliminary measurements of B meson cross sections, b quark cross sections, and b-{bar b} correlated cross sections are presented from the 1992--1993 data obtained at CDF. A search for new states in the 75 pb−1 sample obtained through early 1995 yields no evidence for B{sub c} → J/[psi] - [pi] or [Lambda]{sub b} → J/[psi] - [Lambda](1520).

Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the b[bar b] production cross section and angular correlations between the b and[bar b]-quarks in p[bar p] collisions using the D0 detector at the Fermilab Tevatron operating at[radical]s= 1.8 TeV. The b-quark production cross section for[vert-bar]y[sup b][vert-bar]1.0 and[rho][sub[tau]][sup b] 8 GeV/c is extracted and found to be consistent with next-to-leading order QCD predictions. In addition, the angular correlations between the b and[bar b]-quarks are found to agree in shape with next-to-leading order QCD predictions.

Available in PDF, EPUB and Kindle. Book excerpt: Using data collected during the 1992--1993 collider run at Fermilab, CDF has made measurements of correlated b quark cross sections where one b is detected from the lepton from semileptonic decay and the second b is detected with secondary vertex techniques. We report on measurements of the cross section as a function of the momentum of the second b and as a function of the azimuthal separation of the two b quarks, for transverse momentum of the initial b quark greater than 15 GeV. The vertex reconstruction techniques are valid over a large range in transverse momentum, starting at a minimum of 10 GeV. Results are compared to QCD predictions.

Available in PDF, EPUB and Kindle. Book excerpt: We report on recent results obtained by the D0 and CDF collaborations on the properties of b-quark production and correlations in p[bar p] collisions at [radical]s = 1.8 TeV. The D0 experiment has measured the angular correlations between the b- and [bar b]-quarks using the azimuthal opening angle between their decay muons.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using dimuons collected with the D[null] detector during the 1993- 1995 Tevatron collider run, we have measured the [ital b]-quark cross section and [ital b[anti b]] correlations as given by the difference in azimuthal angle between the two muons. Both measurements agree with the NLO QCD predictions within experimental and theoretical errors.

Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the b-quark production cross section in p{anti p} collisions at (square root)s = 630 GeV. The analysis is based on 340 nb−1 of data collected with the D0 detector at the Fermilab Tevatron Collider. We determine the ratio of the b-quark production cross sections at 630 GeV to 1800 GeV and compare our results with the CDF and UA1 measurements, and with the next-to- leading order QCD predictions.

Available in PDF, EPUB and Kindle. Book excerpt: We report on the status of[ital b] quark and[ital b] hadron production using 110 pb[sup -1] of data collected by the CDF detector between 1992 and 1995. We present the first direct measurement of the ratio of[ital b] quark cross sections at[radical][ital s]= 630 GeV and[radical][ital s]= 1800 GeV, and an update on the measurement of the[ital B] meson differential cross section. We also present measurements of the branching fraction for b[r-arrow] J[Psi] A, and the product of fragmentation fraction and branching fractions for the semileptonic decay b[r-arrow][mu][sup+][ital e][sup -][nu]X. The last two equations were illegible and are a best guess to the original intent.
