| A study of the production of prompt J/ψ mesons contained in jets in proton-proton collisions at s= 8 TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb− 1 collected with the CMS detector at the LHC. For events with at least one observed jet, the angular separation between the J/ψ meson and the jet is used to test whether the J/ψ meson is part of the jet. The analysis shows that most prompt J/ψ mesons having energy above 15 GeV and rapidity| y|< 1 are contained in jets with pseudorapidity| η jet|< 1. The differential distributions of the probability to have a J/ψ meson contained in a jet as a function of jet energy for a fixed J/ψ energy fraction are compared to a theoretical model using the fragmenting jet function approach. The data agree best with fragmenting jet function calculations that use a long-distance matrix element parameter set in which prompt J/ψ mesons are … |
