Sensitivity to Higgs Pseudo-Observables in ZH Production at NLO QCD
We study the sensitivity of the associated Higgs production process $pp \rightarrow ZH$ to anomalous Higgs couplings within the Effective Field Theory framework. Event samples are generated using $ \text{MadGraph5\_aMC@NLO}$ at $\sqrt{s}=13$ TeV using the UFO model HPO\_ewk\_prod\_NLO, and analyzed using a dedicated Python analysis of HepMC events. We investigate several kinematic observables and derive constraints on the EFT parameter $ε_{ZZ}$ using a $χ^2$ statistical analysis. A 95\% confidence level interval $-0.026 < ε_{ZZ} < 0.383 $ is obtained from the simulated data.
