The measurement covers a phase space up to 2 TeVTeV in jet transverse momentum and 2.5 in absolute jet rapidity. The statistical precision of these data leads to stringent constraints on the parton distribution functions of the proton. The data provide important input for the gluon density at high fractions of the proton momentum and for the strong coupling constant at large energy scales. Using predictions from perturbative quantum chromodynamics at next-to-leading order, complemented with electroweak corrections, the constraining power of these data is investigated and the strong coupling constant at the Z boson mass MZMZ is determined to be αS(MZ)=0.1185±0.0019(exp)+0.0060−0.0037(theo)αS(MZ)=0.1185±0.0019(exp)−0.0037+0.0060(theo) , which is in agreement with the world average.enginfo:eu-repo/semantics/restrictedAccessArticle75614200035688830000510.1140/epjc/s10052-015-3499-1Spin correlationsLhc physicsFragmentationScatteringModelSimulationEvolutionToolkit
