Measurement of the double-differential inclusive jet cross section at $\sqrt{s}$ = 13 TeV

A measurement of the double-differential inclusive jet cross section, as a function of jet transverse momentum $p_\mathrm{T}$ and absolute jet rapidity $|y|$, is presented. The analysis is based on a data set of proton-proton collisions acquired by the CMS experiment at the LHC during 2015 at a center-of-mass energy of 13 TeV. The collected data correspond to an integrated luminosity of 72 $\mathrm{pb}^{-1}$ for rapidities up to $|y|=3$ and 45 $\mathrm{pb}^{-1}$ for the forward rapidity region $3.2<|y|<4.7$. Jets are reconstructed with the anti-$k_{\mathrm{T}}$ clustering algorithm for two jet size parameters R=0.7 and R=0.4 in a phase space region covering jet $p_\mathrm{T}$ up to 2 TeV and jet rapidity up to $|y|$ = 4.7. The results are compared to fixed-order predictions of perturbative QCD and to simulations using various Monte Carlo event generators including parton showers, hadronisation, and multiparton interactions.
