We calculate the transverse momentum pT distribution for production of the \ensuremathΥ states in hadronic reactions. For small pT(\ensuremath≤M_\ensuremathΥ), we resum to all orders in the strong coupling \ensuremathαs the process-independent large logarithmic contributions that arise from initial-state gluon showers. We demonstrate that the pT distribution at low pT is dominated by the region of small impact parameter b and that it may be computed reliably in perturbation theory. We express the cross section at large pT by the O(\ensuremathαs3) lowest-order nonvanishing perturbative contribution. Our results are consistent with data from the Fermilab Tevatron collider.
