摘要

This paper reports the measurement of the B meson and b quark cross sections through the decay chain B0 --> J/psi K* (892)0, J/psi --> mu+ mu-, K* (892)0 --> K+ pi-, using 4.3 pb-1 of data collected at the Collider Detector at Fermilab in pBARp collisions at square-root s = 1.8 TeV. We obtain sigma(B) = 1.5 +/- 0.7(stat)+/-0.6(syst) mub for B0 mesons with transverse momentum P(T) > 9.0 GeV/c and rapidity \y\ < 1.0. Using this results, we find sigma(b) = 3.7 +/- 1.6(stat)+/-1.5(syst) mub for b quarks with P(T) > 11.5 GeV/c and rapidity \y\ < 1.0. The b quark cross section is compared to next-to-leading order QCD calculations and previous measurements.
