Multiparton interactions and underlying event : A PYTHIA perspective
We review recent developments in PYTHIA8, focused on heavy ion collisions. The ANGANTYR framework for heavy ion collisions is presented, as well as recent developments of the string shoving model for flow. It is further shown how string shoving can affect jet fragmentation in pp collisions. The effect of adding hadronic rescattering is reviewed, with focus on the nuclear modification factor, and f
