Description

In this talk we discuss the results of a full-simulation study exploring CP violation in Higgs production through ZZ fusion. The study is performed for CLIC running at a centre-of-mass energy of 1.4TeV, assuming that the Higgs boson is realized as a mixture of scalar and pseudoscalar states. By measuring the electron and positron in the final state, the CP-violating mixing angle $\Psi_{\mathrm{CP}}$ can be probed at the HZZ production vertex, and the statistical precision on its measurement determined. This method is complementary to other studies.
