| Özet |
| A measurement of the angular structure of jets containing a prompt D meson and of inclusive jets in proton-proton collisions at the LHC at a center-of-mass energy of 5.02 TeV is presented. The data corresponding to an integrated luminosity of 301 pb were collected by the CMS experiment in 2017. Two jet grooming algorithms, late- and soft drop, are used to study the intrajet radiation pattern using iterative CambridgeAachen declustering. The splitting-angle distributions of jets with transverse momentum () of around 100 GeV, obtained with these two algorithms, show that there is a shift of the distribution for jets containing a prompt D meson with respect to inclusive jets. The shift observed in the late- grooming approach is consistent with the dead-cone effect, whereas the shift for splittings selected with the soft-drop algorithm appears to be dominated by gluon splitting to charm quark-antiquark pairs. The measured distributions are corrected to the particle level and can be used to constrain model predictions for the substructure of high- charm quark jets. |
