Measurement of four-jet differential cross sections in √s=8 TeV proton-proton collisions using the ATLAS detector

ATLAS Collaboration

Original · EN

Differential cross sections for the production of at least four jets have been measured in proton-proton collisions at √s = 8 TeV at the Large Hadron Collider using the ATLAS detector. Events are selected if the four anti-kₜ R=0.4 jets with the largest transverse momentum (pₜ) within the rapidity range |y|<2.8 are well separated (dR min₄ⱼ>0.65), all have pₜ>64 GeV, and include at least one jet with pₜ >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.
