Events are selected if the four anti-k$_{t}$ R = 0.4 jets with the largest transverse momentum (p$_{T}$) within the rapidity range |y| < 2.8 are well separated (ΔR$_{4j}^{min}$  > 0.65), all have p$_{T}$ > 64 GeV, and include at least one jet with p$_{T}$ > 100 GeV. The dataset corresponds to an integrated luminosity of 20.3 fb$^{−}^{1}$ . The cross sections, corrected for detector effects, are compared to leading-order and next-to-leading-order calculations as a function of the jet momenta, invariant masses, minimum and maximum opening angles and other kinematic variables.engjournal article2019-02-04
