Abstract

This paper reports the measurement of the B meson and b quark cross sections through the decay chain B0→J/ψ K*(892)0, J/ψ→μ+μ-, K*(892)0→K+π-, using 4.3 pb-1 of data collected at the Collider Detector at Fermilab in p̄p collisions at qrts=1.8 TeV. We obtain σB=1.5±0.7(stat)±0.6(syst) μb for B0 mesons with transverse momentum PT>9.0 GeV/c and rapidity y<1.0. Using this result, we find σb=3.7±1.6(stat)±1.5(syst) μb 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.
