Abstract
We calculate the cross section for hadroproduction of a pair of heavy quarks in a 3S1 color-singlet state at next-to-leading order in QCD. This corresponds to the leading contribution in the NRQCD expansion for J/psi and Upsilon production. The higher-order corrections have a large impact on the p_T distributions, enhancing the production at high p_T both at the Tevatron and at the LHC. The total decay rate of a 3S1 into hadrons at NLO is also computed, confirming for the first time the result obtained by Mackenzie and Lepage in 1981.
