Description:
'Differential cross-section measurements are presented for the electroweak production of two jets in association with a $ZZ$ 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 
 $\sqrt{s} = 13$ TeV and with an integrated luminosity of 139 fb$^{-1}$. The differential cross-sections are measured 
 in the $Z\rightarrow \ell^+\ell^-$ decay channel ($\ell=e,\mu$) 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. The data are corrected for the effects of detector inefficiency and resolution and are sufficiently 
 precise to distinguish between different state-of-the-art theoretical predictions calculated using Powheg+Pythia8, 
 Herwig7+Vbfnlo and Sherpa 2.2. The differential cross-sections are used to search for anomalous weak-boson 
 self-interactions using a dimension-six effective field theory. The measurement of the signed azimuthal angle between 
 the two jets is found to be particularly sensitive to the interference between the Standard Model and dimension-six 
 scattering amplitudes and provides a direct test of charge-conjugation and parity invariance in the weak-boson self-interactions.
 Note that the default entry point is for the inclusive Z+2jet selections. For the EW-only measurement use the option TYPE=EW_ONLY.
 In both cases, electron and muon channels are to be summed.'
