Fragmentation of jets containing a prompt J/ψ meson in PbPb and pp collisions at s =5.02TeV

Jets containing a prompt 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 . The yield in these jets is evaluated as a function of the jet fragmentation vari...

Descripción
Sumario:Jets containing a prompt 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 . The yield in these jets is evaluated as a function of the jet fragmentation variable z, the ratio of the to the jet . The nuclear modification factor, , 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 yield shows a dependence on z, indicating that the interaction of the with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the meson.
