Determination of CPV Higgs mixing angle in ZZ-fusion at 1.4 TeV CLIC

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 (cid:9) CP can be probed at the HZZ production vertex
