Fragmentation of J/ψ in jets in pp collisions at √s = 5.02 TeV
The fragmentation of jets containing a J/ψ meson is studied in √s = 5.02 TeV pp data using an integrated luminosity of L = 27.39 pb−1. The fraction of the jet transverse momentum pT,jet carried by the J/ψ is measured for prompt J/ψ and J/ψ coming from b hadron decays, named nonprompt. Whereas the...

| Summary: | The fragmentation of jets containing a J/ψ meson is studied in √s = 5.02 TeV pp data using an integrated luminosity
of L = 27.39 pb−1. The fraction of the jet transverse momentum pT,jet carried by the J/ψ is measured for prompt J/ψ
and J/ψ coming from b hadron decays, named nonprompt. Whereas the fragmentation function of nonprompt J/ψ is
well-modeled by simulations using a Monte Carlo generator, the prompt J/ψ are found to be accompanied by a larger
level of jet activity. The fraction of J/ψ mesons that are produced inside a jet is also reported, and found to be larger in
data than in simulation, for both prompt and nonprompt J/ψ. |
