  We present theoretical predictions for the nuclear-induced attenuation of the
differential cross sections for inclusive and tagged b-jet production in heavy
ion collisions at the LHC. We find that for inclusive b-jet production at high
transverse momentum the mass effects are negligible, and that the attenuation
is comparable to the one observed for light jets. On the other hand, for
isolated-photon and B-meson-tagged b-jets the sample of events with heavy
quarks produced at the early stages of the collision is greatly enhanced. Thus,
these tagged b-jet final-states have a much more direct connection to the
physics of b-quark energy loss. We present theoretical predictions for the
quenching of such tagged b-jet events at the LHC and the QGP-induced
modification of the related momentum imbalance and asymmetry. We demonstrate
that these tagged processes can be used to accurately study the physics of
heavy quark production and propagation in dense QCD matter.
