Abstract

Inclusive J/psi and psi(2S) production has been studied in ppBAR collisions at square-root 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 P(T) for J/psi --> mu+mu- and psi(2S) --> mu+mu-. In the kinematic range P(T)>6 GeV/c and Absolute value of eta less-than-or-equal-to 0.5 we get sigma(ppBAR --> J/psiX)B(J/psi --> mu+mu-) = 6.88+/-0.23(stat)-1.08(+0.93)(syst) nb, and sigma(ppBAR --> psi(2S)X)B(psi(2S) --> mu+mu-) = 0.232+/-0.251(stat)-0.032(+0.029)(syst) nb. From these values we calculate the inclusive b-quark production cross section.
