The bb ¯ ¯ bb¯ production cross section and angular correlations in pp ¯ ¯ ¯ pp¯ collisions at s √ s = 1.8 TeV
The bb ¯ ¯ bb¯ production cross section and angular correlations in pp ¯ ¯ ¯ pp¯ collisions at s √ s = 1.8 TeV
We present measurements of the bb-bar Image production cross section and angular correlations using the DØ detector at the Fermilab Tevatron pp-bar Collider operating at ?s = 1.8 TeV. The b quark production cross section for |y^b| < 1.0 and pT^b > 6 GeV/c is extracted from single muon and dimuon data samples. The results agree in shape with the next-to-leading order QCD calculation of heavy flavor production but are greater than the central values of these predictions. The angular correlations between b and bbar quarks, measured from the azimuthal opening angle between their decay muons, also agree in shape with the next-to-leading order QCD prediction.

Abstract
We present measurements of the bb-bar Image production cross section and angular correlations using the DØ detector at the Fermilab Tevatron pp-bar Collider operating at ?s = 1.8 TeV. The b quark production cross section for |y^b| < 1.0 and pT^b > 6 GeV/c is extracted from single muon and dimuon data samples. The results agree in shape with the next-to-leading order QCD calculation of heavy flavor production but are greater than the central values of these predictions. The angular correlations between b and bbar quarks, measured from the azimuthal opening angle between their decay muons, also agree in shape with the next-to-leading order QCD prediction.
