Descripción
A measurement of the double-differential inclusive jet cross section as
a function of the jet transverse momentum p T and the
absolute jet rapidity | y| is presented. Data from LHC proton-proton
collisions at √{s}=8 TeV, corresponding to an integrated luminosity
of 19.7 fb-1, have been collected with the CMS detector. Jets
are reconstructed using the anti- k T clustering algorithm
with a size parameter of 0.7 in a phase space region covering jet p
T from 74 GeV up to 2.5 TeV and jet absolute rapidity up to |
y| = 3.0. The low- p T jet range between 21 and 74 GeV is
also studied up to | y| = 4.7, using a dedicated data sample
corresponding to an integrated luminosity of 5.6 pb-1. The
measured jet cross section is corrected for detector effects and
compared with the predictions from perturbative QCD at next-to-leading
order (NLO) using various sets of parton distribution functions (PDF).
Cross section ratios to the corresponding measurements performed at 2.76
and 7 TeV are presented. From the measured double-differential jet cross
section, the value of the strong coupling constant evaluated at the Z
mass is α S( M Z) = 0.1164 -
0.0043 + 0.0060 , where the errors include the PDF,
scale, nonperturbative effects and experimental uncertainties, using the
CT10 NLO PDFs. Improved constraints on PDFs based on the inclusive jet
cross section measurement are presented. [Figure not available: see
