Next-to-leading order QCD corrections to hadron+jet production in pp collisions at RHIC

We compute the next-to-leading order (NLO) QCD corrections to the spin-independent and spin-dependent cross sections for the production of a single-hadron accompanied by an opposite jet in hadronic collisions. This process is being studied experimentally at RHIC, providing a new tool to unveil the p...
