Measurement and QCD analysis of double-differential inclusive jet cross sections in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Abstract

A measurement of the inclusive jet production in proton-proton collisions at the LHC at $\sqrt{s}$ = 13 TeV is presented. The double-differential cross sections are measured as a function of the jet transverse momentum $p_{\mathrm{T}}$ and the absolute jet rapidity $|y|$. The anti-$k_{\mathrm{T}}$ clustering algorithm is used with distance parameter of 0.4 (0.7) in a phase space region with jet $p_{\mathrm{T}}$ from 97 GeV up to 3.1 TeV and $|y|$ $<$ 2.0. Data collected with the CMS detector are used, corresponding to an integrated luminosity of 36.3 fb${}^{-1}$ (33.5 fb${}^{-1}$). The measurement is used in a comprehensive QCD analysis at next-to-next-to-leading order, which results in significant improvement in the accuracy of the parton distributions in the proton. Simultaneously, the value of the strong coupling constant at the Z boson mass is extracted as ${\alpha }_{\mathrm{S}}$(Z) = 0.1170 $\pm$ 0.0019. For the first time, these data are used in a standard model effective field theory analysis at next-to-leading order, where parton distributions and the QCD parameters are extracted simultaneously with imposed constraints on the Wilson coefficient $c_1$ of 4-quark contact interactions. Note added: in the Addendum to this paper, available as Appendix B in this document, an improved value of ${\alpha }_{\mathrm{S}}$(Z) = 0.1166 $\pm$ 0.0017 has been extracted. This result supersedes the number in the above abstract of the original publication.

Now includes the latest addendum as Appendix B plus the notice of the revised value for ${\alpha }_{\mathrm{S}}$(Z) on the front page.
