Hadron plus photon production in polarized hadronic collisions at next-to-leading order accuracy

[EN]We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, permits us to reconstruct partonic kinematics using experimentally measurable...

description [EN]We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, permits us to reconstruct partonic kinematics using experimentally measurable variables. We study the correlation between the reconstructed momentum fractions and the true partonic ones, which in the polarized case might allow us to reveal the spin-dependent gluon distribution with a higher precision. [ES] Calculamos las correcciones de QCD a orden siguiente al dominante (NLO) para las secciones eficaces polarizadas (y no polarizadas) en la producción de un hadrón acompañado por un fotón directo en el hemisferio opuesto. Este proceso, que se estudia en RHIC, nos permite reconstruir la cinemática partónica utilizando variables experimentalmente medibles. Analizamos la correlación entre las fracciones de momento reconstruidas y las verdaderas fracciones partónicas, lo que, en el caso polarizado, podría permitir revelar la distribución de gluones dependiente del espín con mayor precisión.
