Heavy flavor production
Predictions are presented of total cross sections for charm and bottom quark production in /bar p/p, ..pi../sup /minus//p, and pp interactions at fixed target and collider energies. The calculations are done through next-to-leading order in QCD perturbation theory. The sensitivity is explored of results to the choices of renormalization/evolution scale, parton densities, ..lambda../sub QCD/, and heavy flavor masses. Comparisons with available data show that good agreement is obtained for reasonable values of charm and bottom quark masses and other parameters. Open issues in the interpretation of results are summarized including the large size of the next-to-leading order contributions, proper definition of the gluon density, the nuclear A dependence of charm cross sections, the role of final state interactions, and higher twist effects. 39 refs., 7 figs., 5 tabs.
