Investigations of the impact of the parton shower tuning in Pythia 8 in the modelling of $\mathrm{t\overline{t}}$ at $\sqrt{s}=8$ and 13 TeV

Studies are presented comparing top quark pair differential distribution data collected with the CMS detector at $\sqrt{s}=8$ and 13 TeV to state-of-the-art theoretical predictions. A tuning of POWHEG v2+PYTHIA8 through jet kinematics in top quark pair events and global variables is described and th...
