Abstract
We propose a new dihedral angle observable to measure the CP property of the interaction of top quark and Higgs boson in the production at the 14~TeV LHC. We consider two decay modes of the Higgs boson, and 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 .
