Four-jet double parton scattering production in proton-nucleus collisions within the PYTHIA8 framework

We present our studies of four-jet double parton scattering production in proton-nucleus collisions within the framework of the PYTHIA8 event generator. We demonstrate that double absorptive processes in p A generated by the Angantyr model in PYTHIA8 give an enhancement of the total double parton scattering cross section similar to the predictions by Strikman and Treleani in 2001. Additionally, we discuss how the growth of activity in the direction of a nucleus affects an A scaling of a total double parton scattering cross section in proton-nucleus collisions.
