Measurement of the nuclear modification factor of b-jets in 5.02 TeV Pb+Pb collisions with the ATLAS detector
Original language description
This paper presents a measurement of b-jet production in Pb+Pb and pp collisions at sNN=5.02sNN =5.02 TeV with the ATLAS detector at the LHC. The measurement uses 260 pb−1pb−1 of pp collisions collected in 2017 and 1.4 nb−1nb−1 of Pb+Pb collisions collected in 2018. In both collision systems, jets are reconstructed via the anti-ktkt 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=0.2R=0.2 and R=0.4R=0.4, and only R=0.2R=0.2 jets are used in Pb+Pb collisions. For comparison, inclusive R=0.2R=0.2 jets are also measured using 1.7 nb−1nb−1 of Pb+Pb collisions collected in 2018 and the same pp collision data as the b-jet measurement.
