Results from the ML model vs binning in \(p_{T}^{Z}\), \(O(\Lambda^{-2})\), pair-wise fit

Figure 5.6 of [Gomez Ambrosio et al., 2022].

95% CL intervals on \(n_{eft}=7\) Wilson coefficients relevant for the description of Higgs production in association with a Z boson at the linear \(O(\Lambda^{-2})\) level.

The black cross indicates the SM values used to generate the pseudo-data. We present 95% CL intervals obtained from two-parameter fits, where for each panel the contribution from the operators not shown is set to zero.

We compare the bounds obtained from a binned \(p_{T}^{Z}\) distribution with those from two ML unbinned observables, first when only \(p_{T}^{Z}\) is used for the training and second when \(n_{k} = 7\) kinematic features are used.

See the next page for similar plots, this time obtained at the quadratic \(O(\Lambda^{-4})\) level in the EFT expansion.
