Book Description
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*. Another measurement made using data from the 1988--89 run on the correlated b + {bar b} cross section is also presented.

Book Description
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 Description
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).

Book Description
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.

Book Description
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.

Book Description
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 measurement is also used to extract the inclusive b-quark production cross section for y[sub b]

Book Description
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.
