Abstract: Results are presented from four CDF analyses involving heavy quark productionin proton-antiproton collisions at center of mass energy 1.96 TeV. The shapesof b-jets are found to be broader than inclusive predictions and broader thanboth PYTHIA and HERWIG defaults. A measurement of the production cross sectionfor psi2S is consistent with Run 1 results and with theoretical predictionsassociated with parton distribution function energy dependence. The inclusiveb-jet production cross section is also consistent with theoretical predictionsover six orders of magnitude. The b-bbar differential production cross sectionis compared to several theoretical models and found to be best described byMC@NLO + JIMMY.
