Measurement of the nuclear modification factor for inclusive jets in Pb+Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=5.02$ TeV with the ATLAS detector

Measurements of the yield and nuclear modification factor, $R_{\mathrm{A}\mathrm{A}}$, for inclusive jet production are performed using 0.49 nb${}^{-1}$ of Pb+Pb data at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=5.02$ TeV and 25 pb${}^{-1}$ of $pp$ data at $\sqrt{s}=5.02$ TeV 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 $\mathrm{\mid }y\mathrm{\mid }<2.8$. The magnitude of $R_{\mathrm{A}\mathrm{A}}$ increases with increasing jet transverse momentum, reaching a value of approximately 0.6 at 1 TeV in the most central collisions. The magnitude of $R_{\mathrm{A}\mathrm{A}}$ also increases towards peripheral collisions. The value of $R_{\mathrm{A}\mathrm{A}}$ is independent of rapidity at low jet transverse momenta, but it is observed to decrease with increasing rapidity at high transverse momenta.
