  Vector boson-tagged jet production in collisions of heavy nuclei opens new
opportunities to study parton shower formation and propagation in strongly
interacting matter. It has been argued to provide a golden channel that can
constrain the energy loss of jets in the quark-gluon plasma created in heavy
ion reactions. We present theoretical results for isolated photon-tagged and
$Z^0$ boson-tagged jet production in Pb+Pb collisions with $\sqrt{s_{NN}} =
5.02$ TeV at the LHC. Specifically, we evaluate the transverse momentum
imbalance ${\rm x_{JV}}$ distribution and nuclear modification factor ${\rm
I_{AA}}$ of tagged jets and compare our theoretical calculations to recent
experimental measurements by ATLAS and CMS collaborations. Our analysis, which
includes both collisional and radiative energy losses, sheds light on their
relative importance versus the strength of jet-medium interactions and helps
quantify the amount of out-of-cone radiation of predominantly prompt
quark-initiated jets.
