In high energy proton-proton collisions, collimated sprays of particles, called jets, result from hard scattered quarks or gluons. Jets are copiously produced in these collisions; however, the dynamic process through which quarks and gluons, collectively referred to as partons, become bound state hadrons is still not well understood. Jets provide an excellent tool to study this process as they are proxies for the scattered parton; therefore, final-state hadrons can be measured with respect to an observable that is correlated to the scattered parton. The LHCb experiment is in an excellent position to measure hadrons within jets due to its excellent tracking and particle-identification capabilities. In this talk, new measurements of charged hadrons within jets measured opposite a $Z$ boson will be presented from the LHCb collaboration.
