Measurement of multidifferential cross sections for dijet production in proton-proton collisions at √s=13TeV
Original language description
A measurement of the dijet production cross section is reported based on proton-proton collision data collected in 2016 at root s = 13 TeV by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of up to 36.3 fb(-1). Jets are reconstructed with the anti-k(T) algorithm for distance parameters of R = 0.4 and 0.8. Cross sections are measured double-differentially (2D) as a function of the largest absolute rapidity vertical bar y vertical bar(max) of the two jets with the highest transverse momenta p(T) and their invariant mass m(1,2), and triple-differentially (3D) as a function of the rapidity separation y*, the total boost y(b), and either m(1,2) or the average p(T) of the two jets. The cross sections are unfolded to correct for detector effects and are compared with fixed-order calculations derived at next-to-next-to-leading order in perturbative quantum chromodynamics. The impact of the measurements on the parton distribution functions and the strong coupling constant at the mass of the Z boson is investigated, yielding a value of alpha(S)(m(Z)) = 0.1179 +/- 0.0019.
