- Аннотация: A measurement of the dijet production cross sec-tion is reported based on proton–proton collision data collected in 2016 at √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 |y|_max of the two jets with the highest transverse momenta pT 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 α_S(m_Z ) = 0.1179 ± 0.0019.
