B. Abbott et al., The b(b)over-bar production cross section and angular correlations in p(p)over-bar collisions at root s = 1.8 TeV, PHYS LETT B, 487(3-4), 2000, pp. 264-272
We present measurements of the b (b) over bar production cross section and
angular correlations using the D phi detector at the Fermilab Tevatron p (p
) over bar Collider operating at root s = 1.8 TeV. The b quark production c
ross section for /y(b)/ < 1.0 and P-T(b) > 6 GeV/c is extracted from the si
ngle muon and dimuon data samples. The results agree in shape with me next-
to-leading order QCD calculation of heavy flavor production but are greater
than the central values of these predictions. The angular correlations bet
ween b and (b) over bar quarks, measured from the azimuthal opening angle b
etween their decay muons, also agree in shape with the next-to-leading orde
r QCD prediction. (C) 2000 Elsevier Science B.V. All rights reserved.
