abstract

  • 1994 The American Physical Society This paper reports the measurement of the B meson and b quark cross sections through the decay chain B0J/ K*(892)0, J/+-, K*(892)0K+-, using 4.3 pb-1 of data collected at the Collider Detector at Fermilab in pp collisions at qrts=1.8 TeV. We obtain B=1.50.7(stat)0.6(syst) b for B0 mesons with transverse momentum PT>9.0 GeV/c and rapidity y<1.0. Using this result, we find b=3.71.6(stat)1.5(syst) b for b quarks with PT>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.
