Description

The differential distributions of jet fragmentation probability as a function of jet energy for a fixed J/psi energy fraction z are compared to a theoretical model based on the fragmenting jet function (FJF) approach. The analysis is based on pp collisions at sqrt(s) = 8 TeV, corresponding to an integrated luminosity of 19.1 fb−1. These data distingush clearly between different nonrelativistic quantum chromodynamics (NRQCD) long distance matrix element (LDME) parameter sets and also between different NRQCD terms.
