Abstract

We study the sensitivity of the associated Higgs production process pp → ZH to anomalous Higgs couplings within the Effective Field Theory framework. Event samples are generated using $ \text{MadGraph5\_aMC@NLO}$ at √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 εZZ using a χ2 statistical analysis. A 95\% confidence level interval $-0.026 < ε_{ZZ} < 0.383 $ is obtained from the simulated data.
