Description
In spite of the recent progress in both theoretical and experimental studies many aspects of $\textit{multiple parton interactions}$ (MPI) still require a detail investigation. In particular, $\textit{double parton scattering}$ (DPS) processes can play a dominant role for some specific kinematic regions of multi-jet production, especially in $\textit{proton-nucleus}$ (pA) collisions where the total DPS cross section is approximately $\sim$3A times bigger
as the corresponding total DPS cross section in $\textit{proton-proton}$ (pp) collisions.
In this talk I will discuss the DPS in the four-jet and three-jet plus gamma production processes in pp and pA collisions.
Specifically the impact of parton shower effects on predictions for DPS sensitive observables, the role of nuclear effects
and the dependence of the DPS cross sections on different kinematical cuts and phenomenological assumptions.
