| Özet |
| Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. Here, the cross section ratio of excited and ground state vector mesons is measured as a function of the charged-particle multiplicity in proton-lead () collisions at a center-of-mass (CM) energy per nucleon pair of 8.16 TeV. The data corresponding to an integrated luminosity of were collected using the CMS detector. The ratio is measured separately for prompt and nonprompt charmonia in the transverse momentum range and in four rapidity ranges spanning . For the first time, a statistically significant multiplicity dependence of the prompt cross section ratio is observed in proton-nucleus collisions. There is no clear rapidity dependence in the ratio. The prompt … |
