title: "Table 38" of "Measurements of the inclusive and differential production cross sections of a top-quark-antiquark pair in association with a $Z$ boson at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: The normalised particle-level differential cross-section measured in the fiducial phase-space as a function of the absolute value of rapidity of the $Z$ boson in the 3$\ell$+4$\ell$ channel. The uncertainty is decomposed into four components which are the signal modelling uncertainty, the background modelling uncertainty, the experimental uncertainty, and the data statistical uncertainty.

- Two orthogonal regions combined for inclusive measurement, different region for differential measurement.
- $b$-jets requirements: pseudo-continuous $b$-tagging with different working points for inclusive measurement, fixed 85% $b$-tagging working point for differential measurement. 
- At least 3 (inclusive and differential region) or 4 (inclusive region) jets

The fiducial regions for the tetralepton channel are defined as:

- At least 2 jets.
- $E_{T}^{miss}$ requirements (depending on the region) for suppresion of $ZZ$+jets background.
