We study momentum imbalance as a function of jet asymmetry in high-energy heavy-ion collisions. We produce high momentum partons using 2->2 and 2->3 pQCD LO events. The produced partons lose energy within the QGP and hadronize collinearly when they leave it. The energy and momentum deposited into the plasma are described using linear viscous hydrodynamics. We find that the shape of the asymmetry observed by the CERN-CMS Collaboration can be attributed to parton energy loss in the medium and that a good description of data is achieved when a large portion of the jet events is originated from 2->2 parton events but that this description improves when we include a small but sizable contribution from 2->3 parton processes. We also show a summary of on-going extensions to this work in the study of transport coefficients and flow.
