英文摘要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 root snn= 5.02 tev, as well as results from charm quark jets in proton-proton (pp) collisions at root 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 root snn=5.02 tev of r-pa= 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 root s=2.76 and 5.02tev, and is independent of the jet transverse momentum from 55 to 400 gev/c.
