Description

In this talk we discuss the CP violation in the Higgs sector under assumption that Higgs is a mixture of CP even and odd states. Study is done in ZZ-fusion, at the intermediate energy stage of CLIC, in full simulation of a detector for CLIC and machine and physics related backgrounds. By measuring the properties of electron and positron in the final state, selecting the Higgs dominant decay to b$\bar{\mathrm{b}}$ to reduce backgrounds, we discuss the statistical precision of CP-violating mixing angle measurement with 2.5 ab$^{-1}$ of data.
