Abstract

Measurements of the yield and nuclear modification factor, RAA, for inclusive jet production are performed using 0.49nb−1of Pb+Pb data at √sNN=5.02TeVand 25pb−1of pp data at √s=5.02TeVwith the ATLAS detector at the LHC. Jets are reconstructed with the anti-kt algorithm 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 RAA increases with increasing jet transverse momentum, reaching a value of approximately0.6 at 1TeVin the most central collisions. The magnitude of RAA also increases towards peripheral collisions. The value of RAA is independent of rapidity at low jet transverse momenta, but it is observed to decrease with increasing rapidity at high transverse momenta.
