Differential cross-section measurements are presented for the electroweak production of two jets in association with a Z boson. These measurements are sensitive to the vector-boson fusion production mechanism and provide a fundamental test of the gauge structure of the Standard Model. The analysis is performed using proton–proton collision data collected by ATLAS at s=13 TeVsqrt{s}=13 hbox {TeV}s ​=13 TeV and with an integrated luminosity of 139 fb−1139 hbox {fb}^{-1}139 fb−1. The differential cross-sections are measured in the Z→ℓ+ℓ−Z ightarrow ell ^+ell ^-Z→ℓ+ℓ− decay channel (ℓ=e,μell =e,mu ℓ=e,μ) as a function of four observables: the dijet invariant mass, the rapidity interval spanned by the two jets, the signed azimuthal angle between the two jets, and the transverse momentum of the dilepton pair.
