Measurement and QCD analysis of double-differential inclusive jet cross sections in pp collisions at s = 8 $$ \backslashsqrt{s}=8 $$ TeV and cross section ratios to 2.76 and 7 TeV

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 $$ \backslashsqrt{s}=8 $$ TeV, corresponding to an integrated luminosity of 19.7 fb−1,...
