Description

Inclusive J/ψ and ψ(2S) production has been studied in bar pp collisions at √s =1.8 TeV using 2.6±0.2 pb-1 of data taken with the Collider Detector at Fermilab. The products of production cross section times branching fraction were measured as functions of PT for J/ψ→μ+μ- and ψ(2S)→μ+μ-. In the kinematic range PT>6 GeV/c and |η|≤0.5 we get σ(bar pp→J/ψ X)B(J/ψ→μ+μ-) =6.88±0.23(stat)-1.08+0.93(syst) nb, and σ(bar pp→ψ(2S)X)B(ψ(2S)→μ+μ-) =0.232±0.051(stat)-0.032+0.029(syst)nb. From these values we calculate the inclusive b-quark production cross section
