Dijet and photon-jet correlations in proton-proton collisions at RHIC

Nuclear Theory 2011-07-19 v1 Astrophysics High Energy Physics - Phenomenology

Abstract

We discuss correlations in azimuthal angle as well as correlations in two-dimensional space of transverse momenta of two jets as well as photon and jet. Some ktk_t-factorization subprocesses are included for the first time in the literature. Different unintegrated gluon/parton distributions are used in the ktk_t-factorization approach. The results depend on UGDF/UPDF used. The collinear NLO 232 \to 3 contributions dominate over ktk_t-factorization cross section at small relative azimuthal angles as well as for asymmetric transverse momentum configurations.
