Jets are selected to be in the transverse momentum range of 30<pT<40GeV. The J/ψ yield in these jets is evaluated as a function of the jet fragmentation variable z, the ratio of the J/ψ pT to the jet pT. The nuclear modification factor, RAA, 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. ? 2021 The Author(s)CMS; Heavy ions; Jets; Quarkonia;[SDGs]SDG7journal article10.1016/j.physletb.2021.1368422-s2.0-85122614636
