Fragmentation of jets containing a prompt J$$/\psi$$ meson in PbPb and pp collisions at $$\sqrt{s_\mathrm{NN}} =$$ 5.02 TeV
Abstract
Jets containing a prompt J$$/\psi$$ 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 $$\lt p_\mathrm{T} \lt$$ 40 GeV. The J$$/\psi$$ yield in these jets is evaluated as a function of the jet fragmentation variable $$z$$, the ratio of the J$$/\psi$$$$p_\mathrm{T} $$ to the jet $$p_\mathrm{T}$$. The nuclear modification factor, $$R_\mathrm{AA}$$, 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$$/\psi$$ yield shows a dependence on $$z$$, indicating that the interaction of the J$$/\psi$$ with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the J$$/\psi$$ meson.
