    <subfield code="a">&lt;p&gt;This paper presents a measurement of b-jet production in Pb+Pb and pp collisions at     $\sqrt{{s}_{{}_{\text{NN}}}}=5.02$   TeV with the ATLAS detector at the LHC. The measurement uses 260     ${\text{pb}}^{-1}$   of pp collisions collected in 2017 and 1.4     ${\text{nb}}^{-1}$   of Pb+Pb collisions collected in 2018. In both collision systems, jets are reconstructed via the anti-    ${k}_{t}$   algorithm. The b-jets are identified from a sample of jets containing muons from the semileptonic decay of b-quarks using template fits of the muon momentum relative to the jet axis. In pp collisions, b-jets are reconstructed for radius parameters     $R=0.2$   and     $R=0.4$  , and only     $R=0.2$   jets are used in Pb+Pb collisions. For comparison, inclusive     $R=0.2$   jets are also measured using 1.7     ${\text{nb}}^{-1}$   of Pb+Pb collisions collected in 2018 and the same pp collision data as the b-jet measurement. The nuclear modification factor,     ${R}_{\text{AA}}$  , is calculated for both b-jets and inclusive jets with     $R=0.2$   over the transverse momentum range of 80–290 GeV. The nuclear modification factor for b-jets decreases from peripheral to central collisions. The ratio of the b-jet     ${R}_{\text{AA}}$   to inclusive jet     ${R}_{\text{AA}}$   is also presented and suggests that the     ${R}_{\text{AA}}$   for b-jets is larger than that for inclusive jets in central Pb+Pb collisions. The measurements are compared with theoretical calculations and suggest a role for mass and colour-charge effects in partonic energy loss in heavy-ion collisions.&lt;/p&gt;</subfield>
