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 y+jet and Z+jet processes at 2.76 TeV and 5.02 TeV.Comment: 8 pages, v2: version to be publishe
