Abstract

A measurement of the fragmentation properties of jets containing Υ(nS) mesons using proton-proton collision data at √s = 13 TeV, corresponding to an integrated luminosity of 138 fb−1, is presented. The Υ(nS) mesons associated with jets are reconstructed via their decays producing pairs of oppositely charged muons. The longitudinal and transverse projections of the momenta of the Υ(nS) mesons along the momenta of the corresponding jets are studied. The results are compared with Monte Carlo predictions, including recent developments in the modelling of quarkonia production in parton showers. The description of the data by these Monte Carlo predictions is found to be unsatisfactory, leaving room for improvements in the modelling of such processes.
