This study utilises the Higgs Characterization model to investigate the $CP$properties of the Higgs coupling to the top quark using the $tH$ and$t\bar{t}H$ generation processes. This is done via simulations of proton-protoncollisions with ATLAS detector conditions, which are calculated for sevendifferent $CP$ eigenstates using MadGraph5_aMC@NLO. Three orthogonal categoriesof cuts are subsequently implemented to find the cut efficiencies, which areused in conjunction with the cross-section to find the signal strength.Comparing the signal strength with experimental results shows that one cannotyet conclusively rule out any Higgs $CP$ eigenstates. Analysing histogramsshowed that the most $CP$ sensitive variables were the transverse momenta ofthe Higgs, leptons and photons, which showed a hardening as the Higgs couplingbecame $CP$ odd.
