Abstract

We study the transverse momentum distribution for a pair of heavy quarks produced in hadronhadron interactions. Predictions for the large transverse momentum region are based on exact order \ensuremathα_s³ QCD perturbation theory. For the small transverse momentum region, we use techniques for all orders resummation of leading logarithmic contributions associated with initial state soft gluon radiation. The combination provides the transverse momentum distribution of heavy quark pairs for all transverse momenta. Explicit results are presented for cc pair production at the Fermilab Tevatron collider and for bb pair production at fixed target energies.
