| Abstract: The double-differential inclusive jet cross section is measured as a function of jet transverse momentum ($p_\mathrm{T}$) and absolute rapidity ($|y|$) with proton-proton collision data from the CMS experiment at the LHC. The measurement is performed with data collected in 2013 at $\sqrt{s} =$ 2.76 TeV and corresponding to integrated luminosity of 5.43 pb$^{-1}$. Jets are reconstructed within the $p_\mathrm{T}$ range of 74 to 592 GeV and $|y|$ range of 0.0 to 3.0 using the anti-k$_T$ algorithm with $R = 0.7$. The reconstructed jet spectrum is unfolded to the particle level and compared to QCD predictions at next-to-leading order. The theoretical predictions are provided for five different sets of parton distribution functions and are corrected for non-perturbative effects. A theory-normalized cross section ratio is calculated using the measurements at $\sqrt{s} = $ 2.76 TeV and 8 TeV. The predictions of QCD are tested in a previously unprobed kinematic regime at 2.76 TeV center-of-mass energy. A ratio to the measured inclusive jet cross section at $\sqrt{s} = $ 8 TeV is calculated. | ||
