  We have previously introduced a hybrid strong/weak coupling model for jet
quenching in heavy ion collisions that describes the production and
fragmentation of jets at weak coupling, using PYTHIA, and describes the rate at
which each parton in the jet shower loses energy as it propagates through the
strongly coupled plasma, dE/dx, using an expression computed holographically at
strong coupling. The model has a single free parameter that we fit to a single
experimental measurement. We then confront our model with experimental data on
many other jet observables, focusing here on boson-jet observables, finding
that it provides a good description of present jet data. Next, we provide the
predictions of our hybrid model for many measurements to come, including those
for inclusive jet, dijet, photon-jet and Z-jet observables in heavy ion
collisions with energy $\sqrt{s}=5.02$ ATeV coming soon at the LHC. As the
statistical uncertainties on near-future measurements of photon-jet observables
are expected to be much smaller than those in present data, with about an order
of magnitude more photon-jet events expected, predictions for these observables
are particularly important. We find that most of our pre- and post-dictions do
not depend sensitively on the form we choose for the rate of energy loss dE/dx
of the partons in the shower. This gives our predictions considerable
robustness. To better discriminate between possible forms for the rate of
energy loss, though, we must turn to intrajet observables. Here, we focus on
ratios of fragmentation functions. We close with a suggestion for a particular
ratio, between the fragmentation functions of inclusive and associated jets
with the same kinematics in the same collisions, which is particularly
sensitive to the x- and E-dependence of dE/dx, and hence may be used to learn
which mechanism of parton energy loss best describes the quenching of jets.
