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