We report the first direct measurement of dead-cone effect at colliders, using iterative jet declustering techniques in pp collisions $\sqrt{s} = 13$ TeV. The procedure exposes splittings $\rm{D^{0}}$ mesons shower, by iteratively angular ordered C/A tree. splitting history meson initiated is mapped onto Lund Plane, where appropriate cuts can be made to suppress hadronisation effects. reported ...
