Description

We propose a new dihedral angle observable to measure the CP property of the interaction of top quark and Higgs boson in the ttH production at the 14 TeV LHC. We consider two decay modes of the Higgs boson, H → bb and H → γγ, and show that the dihedral angle distribution is able to distinguish the CP-even and the CP-odd hypothesis at 95% confidence level with an integrated luminosity of ∼180 fb^−1.
