摘要：

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