RESUMMATION
 
Description We investigate single-inclusive high-p(T) jet production in longitudinally polarized pp collisions at the Relativistic Heavy Ion Collider, with particular focus on the algorithm adopted to define the jets. Following and extending earlier work in the literature, we treat the jets in the approximation that they are rather narrow, in which case analytical results for the corresponding next-to-leading order partonic cross sections can be obtained. This approximation is demonstrated to be very accurate for practically all relevant situations, even at Tevatron and LHC energies. We confront results for cross sections and spin asymmetries based on using cone and k(t)-type jet algorithms. We find that jet cross sections at the Relativistic Heavy Ion Collider can differ significantly depending on the algorithm chosen, but that the spin asymmetries are rather robust. Our results are also useful for matching threshold-resummed calculations of jet cross sections to fixed-order ones.
