| Abstract: The inclusive jet cross section is differentially measured in bins of jet transverse momentum $p_{\mathrm{T}}$ and rapidity $y$. The measurement is performed using proton-proton collision data at $\sqrt{s} = $ 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb$^{-1}$. The jets are reconstructed with the anti-$k_{\mathrm{T}}$ algorithm using a distance parameter of $R = $ 0.4, within the rapidity interval $|y| < $ 2, across the kinematic range 0.06 $ < p_{\mathrm{T}} < $ 1 TeV. The jet cross section is unfolded from detector-level to particle-level using the measured jet response and resolution. The measurement is compared with perturbative QCD predictions, calculated at both next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). The prediction is corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization and factorization scale $\mu$. The NNLO prediction reproduces the measured cross section better than NLO does, and the NNLO prediction is also significantly less dependent on the choice of $\mu$. | ||
