Measurement of the inclusive bottom quark production cross section and bottom anti-bottom azimuthal angle correlations in proton anti-proton collisions at center-of-mass energy = 1.8 TeV

摘要

Using dimuon events produced in proton-antiproton collisions at √s = 1.8 TeV at the D⊘ detector, the integrated inclusive b-quark production cross section has been extracted. The inclusive b-quark production cross section for Pᵇ(T) > 9 GeV/c is 2.61 ± 0.07(Stat) ± 1.13(Syst) nb. The cross section, dσ/dΔφ(μμ) , where Δφ(μμ), is the azimuthal angle difference between the dimuons, has also been measured. Both measurements are in good agreement with next-to-leading order QCD predictions.
