Processes in which a jet recoils against an electroweak boson complement studies of jet quenching in heavy ion collisions at the LHC. As the boson does not interact strongly it escapes the dense medium unmodified and thus provides a more direct access to the hard scattering kinematics than can be obtained in di-jet events. First measurements of jet modification in these processes are now available from the LHC experiments and will improve greatly with better statistics in the future. We present an extension of Jewel to boson–jet processes. Jewel is a dynamical framework for jet evolution in a dense background based on perturbative QCD that is in agreement with a large variety of jet observables. We also obtain a good description of the CMS and ATLAS data for γ +jet and Z+jet processes at 2.76 and 5.02 TeV.
