Measurement of the nuclear modification factor for inclusive jets in Pb+Pb collisions at s NN =5.02 TeV with the ATLAS detector
Measurements of the yield and nuclear modification factor, R AA , for inclusive jet production are performed using 0.49 nb −1 of Pb+Pb data at s NN =5.02TeV and 25 pb −1 of Pb+Pb data at s=5.02TeV with the ATLAS detector at the LHC. Jets are reconstructed with the anti-k t algorithm with radius para...

| Sumario: | Measurements of the yield and nuclear modification factor, R AA , for inclusive jet production are performed using 0.49 nb −1 of Pb+Pb data at s NN =5.02TeV and 25 pb −1 of Pb+Pb data at s=5.02TeV with the ATLAS detector at the LHC. Jets are reconstructed with the anti-k t algorithm with radius parameter R=0.4 and are measured over the transverse momentum range of 40–1000 GeV in six rapidity intervals covering |y|<2.8. The magnitude of R AA increases with increasing jet transverse momentum, reaching a value of approximately 0.6 at 1 TeV in the most central collisions. The magnitude of R AA also increases towards peripheral collisions. The value of R AA is independent of rapidity at low jet transverse momenta, but it is observed to decrease with increasing rapidity at high transverse momenta. © 2019 The Author |
