We study the azimuthal asymmetries for quark pair production in proton-nucleus collisions using a hybrid approach in which the nucleus is treated in the color glass condensate framework, while the Lipatov approximation is applied on the proton side. Our treatment goes beyond the large-N-c limit. We particularly focus on the so-called correlation limit where the imbalance of the transverse momentum of the quark pair is much smaller than the outgoing individual quark transverse momenta. In this kinematic region, a matching between the hybrid approach and a factorization in terms of transverse momentum-dependent parton distributions has been found. It is shown which of the various unpolarized and linearly polarized gluon transverse momentum-dependent parton distributiondistributions contribute to cos 2 phi and cos 4 phi modulations of quark pair production.
