One of the most poorly understood phenomenon in hadron collisions, is the so called multiple parton interaction (MPI). Apart from one quark or gluon each from each colliding proton, additional quarks or gluons can interact as well, and these can not be calculated from first principles. The concept of rescattering has been introduced recently in Pythia8 event generator, where particles originating from these secondary interactions can interact again with quarks or gluons from incoming protons. In this paper, we look at events with a Z-boson, to find observables which can potentially be sensitive to this rescattering effect. While jet-balance observables do not show visible difference, charged particle distributions in different azimuthal regions show some difference. The parameters controlling MPI can be tuned to give a good description of data with rescattering.
