Inclusive jet production

Resumen/Abstract

The value of the strong coupling aS is determined in a comprehensive analysis at next-to-next-to-leading order accuracy in quantum chromodynamics. The analysis uses double-differential cross section measurements from the CMS Collaboration at the CERN LHC of inclusive jet production in proton-proton collisions at centre-ofmass energies of 2.76, 7, 8, and 13 Te V, combined with inclusive deep-inelastic data from HERA. The value aS(mZ) = 0.1176 +0.0014 -0.0016 is obtained at the scale of the Z boson mass. By using the measurements in different intervals of jet transverse momentum, the running of aS is probed for energies between 100 and 1600Ge V.
