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

Abstract

AbstractA measurement of the inclusive jet production in proton-proton collisions at the LHC at$$ \sqrt{s} $$<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msqrt><mml:mi>s</mml:mi></mml:msqrt></mml:math>= 13 TeV is presented. The double-differential cross sections are measured as a function of the jet transverse momentumpTand the absolute jet rapidity|y|. The anti-kTclustering algorithm is used with distance parameter of 0.4 (0.7) in a phase space region with jetpTfrom 97 GeV up to 3.1 TeV and|y| &lt;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 asαS(mZ) = 0.1170±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 coefficientc1of 4-quark contact interactions.
