Abstract
We compare results of kt-factorization approach and next-to-leading order collinear-factorization approach for photon-jet correlations in pp and pp collisions at RHIC, Tevatron and LHC energies. We discuss correlations in azimuthal angle as well as in two-dimensional space of transverse momenta of photon and jet. Different unintegrated parton distributions (UPDF) are included in the kt -factorization approach. The results depend on UPDFs used. The results of NLO collinearfactorization are shown for comparison.
