Issue Date: | 2019 | Serial title, monograph or event: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 790 | Abstract: | Measurements of the yield and nuclear modification factor, RAA, for inclusive jet production are performed using 0.49nb−1of Pb+Pbdata at √sNN=5.02TeVand 25pb−1of ppdata at √s=5.02TeVwith the ATLAS detector at the LHC. Jets are reconstructed with the anti-ktalgorithm with radius parameter R =0.4and are measured over the transverse momentum range of 40–1000GeVin six rapidity intervals covering |y| <2.8. The magnitude of RAAincreases with increasing jet transverse momentum, reaching a value of approximately0.6 at 1TeVin the most central collisions. The magnitude of RAAalso increases towards peripheral collisions. The value of RAAis independent of rapidity at low jet transverse momenta, but it is observed to decrease with increasing rapidity at high transverse momenta. | URI: | https://hdl.handle.net/10316/107216 | DOI: | 10.1016/j.physletb.2018.10.076 | Rights: | openAccess |
