We calculate the next-to-leading order QCD corrections to quark-quark annihilation to a scalar resonant state (diquark) in a color representation of antitriplet or sextet at the Tevatron and LHC energies. At the LHC, we find the enhancement ( K-factor) for the antitriplet diquark is typically about 1.31-1.35, and for the sextet diquark is about 1.22 1.32 for initial-state valence quarks. The full transverse-momentum spectrum for the diquarks is also calculated at the LHC by performing the soft gluon resummation to the leading logarithm and all orders in the strong coupling.
