### Description

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. In this poster, we report in detail the new measurement of b-tagged jets production reconstructed from a jet-associated muon in $pp$ and Pb+Pb at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV collision energy using the large statistics of the recently collected 2018 ATLAS data.
