The measurement of modification of jet yields in heavy-ion collisions provides a powerful method to probe the dynamics of the hot, dense medium formed in these collisions at the LHC. Jet quenching in heavy-ion collisions is expected
to depend on the flavor of the fragmenting parton. For light partons, energy loss via gluon bremsstrahlung is expected to dominate, while in the case of heavy-quark-initiated-jets, collisional energy loss may play a more important role. This poster reports the new measurement of b-tagged jets production in $pp$ and Pb+Pb at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV collision energy using the large statistics Pb+Pb data sample collected with ATLAS in 2018 where the tagging utilizes muon-to-jet association.
