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.eninfo:eu-repo/semantics/openAccess#BAŞV!Article85110.1140/epjc/s10052-024-13606-82-s2.0-105001121237Q1WOS:001412079300001Q20000-0002-9860-91850000-0001-6627-87160000-0003-2205-11000000-0001-8057-91520000-0002-9779-35660000-0002-8553-45080000-0003-1581-6152
