摘要: The Higgs boson $H$ has the largest coupling to top quark $t$ among standard model (SM) fermions. This is one of ideal places investigate new physics beyond SM. In this work, we study potential determining $CP$ properties at LHC and future 33 TeV 100 $pp$ colliders by analysing various operators formed from final states variables in $t\bar{t}H$ production. discrimination power SM obtained with reconstructed $ H\to \gamma \gamma$ b \bar{b}$. We find that $t\bar{t}b\bar{b}$ process can provide more than 3$\sigma$ 300 $fb^{-1}$ integrated luminosity a wide range allowed couplings for LHC, colliders. For $t\bar{t}\gamma\gamma$ will be below while colliders, sensitivity reached.
