Description
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} = 5.02TeV, as well as results from charm quark
jets in proton-proton (pp) collisions at √{ s} = 2.76 and 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
400 GeV/ c in pPb collisions at √{sNN} = 5.02TeV
of 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
by PYTHIA 6 for pp collisions at √{ s} = 2.76 and 5.02TeV, and is
independent of the jet transverse momentum from 55 to 400 GeV/ c.
