The $R_{\rm g}$ (left) and $n_{\rm SD}$ (right) distributions of prompt $\Dzero$-tagged jets compared to those of inclusive jets for $15 \leq p_{\rm T}^{\rm jet\,ch} \leq 30$ GeV/$c$ in pp collisions at $\sqrt{s}$ = 13 TeV. Model/data ratios are shown in the bottom panels for PYTHIA 8  and POWHEG  + PYTHIA 6  simulations.
