| dc.description.abstract | 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 √sNN=5.02 TeV, as well as results from charm quark jets in proton–proton (pp) collisions at √s=2.76and 5.02TeV. 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 400GeV/cin pPb collisions at √sNN=5.02 TeVof RpA=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 bypythia6 for pp collisions at √s=2.76and 5.02TeV, and is independent of the jet transverse momentum from 55 to 400GeV/c. | en_US |
