Jets containing a prompt J / ψ meson are studied in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV, using the CMS detector at the LHC. Jets are selected to be in the transverse momentum range of 30 < p T < 40 GeV . The J / ψ yield in these jets is evaluated as a function of the jet fragmentation variable z , the ratio of the J / ψ p T to the jet p T . The nuclear modification factor, R AA , is then derived by comparing the yield in lead-lead collisions to the corresponding expectation based on proton-proton data, at the same nucleon-nucleon center-of-mass energy. The suppression of the J / ψ yield shows a dependence on z , indicating that the interaction of the J / ψ with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the J / ψ meson.
