| Özet |
| The CMS Collaboration presents the first measurement of the differential cross section of jets from charm quarks produced in proton–lead (pPb) collisions at a nucleon–nucleon center-of-mass energy of s NN= 5.02 TeV, as well as results from charm quark jets in proton–proton (pp) collisions at s= 2.76 and 5.02 TeV. By comparing the yields of the pPb and pp collision systems at the same energy, a nuclear modification factor for charm jets from 55 to 400 GeV/c in pPb collisions at s NN= 5.02 TeV of R p A= 0.92±0.07 (stat)±0.11 (syst) is obtained. This is consistent with an absence of final-state energy loss for charm quarks in pPb collisions. In addition, the fraction of jets coming from charm quarks is found to be consistent with that predicted by pythia 6 for pp collisions at s= 2.76 and 5.02 TeV, and is independent of the jet transverse momentum from 55 to 400 GeV/c. |
