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 kt-factorization subprocesses are included for the first time in the literature. Different unintegrated gluon/parton distributions are used in the kt-factorization approach. The results depend on UGDF/UPDF used. The collinear NLO 2 ↦3 contributions dominate over kt-factorization cross section at small relative azimuthal angles as well as for asymmetric transverse momentum configurations.
