dc.description.abstractA study of the production of prompt J/psi mesons contained in jets in proton-proton collisions at root 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/psi meson and the jet is used to test whether the J/psi meson is part of the jet. The analysis shows that most prompt J/psi mesons having energy above 15 GeV and rapidity vertical bar y vertical bar < 1 are contained in jets with pseudorapidity vertical bar eta(jet)vertical bar < 1. The differential distributions of the probability to have a J/psi meson contained in a jet as a function of jet energy for a fixed J/psi 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/psi mesons are predicted to be unpolarized. This technique demonstrates a new way to test predictions for prompt J/psi production using nonrelativistic quantum chromodynamics. (C) 2020 Elsevier B.V.en_US
dc.description.sponsorshipWe thank Ira Rothstein, Matthew Baumgart, and Prashant Shrivastava for their help in creating the tables of the predictions from their fragmenting jet function model to compare with our data. We thank Nora Brambilla for editorial input and theoretical guidance.
