Abstract:

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 polarized gluon distribution Δg. We perform a detailed analysis of the phenomenological impact of the observable at NLO accuracy and show that the preliminary data by the STAR collaboration confirms the idea of a small gluon polarization in the 0.05 x 0.3 range. © 2009 The American Physical Society.
