First Direct Observation of the Dead-Cone Effect
We report the first direct measurement of the dead-cone effect at colliders, using iterative jet declustering techniques in pp collisions at s=13TeV . The procedure exposes the splittings of D 0 mesons in the jet shower, by iteratively declustering the angular ordered C/A tree. The splitting history...
