Abstract: We demonstrate how the transverse + − spin correlations can be used to determine whether a decaying Higgs boson is a mixed CP eigenstate, thereby directly probe the presence of CP violation in the neutral Higgs boson sector. We investigate the subsequent decay chain H ! + − ! +¯ − ! + 0¯ − 0 . The prospects for the measurement of the pseudoscalar admixture in the H + − coupling to a Standard Model Higgs boson with a mass of 120 GeV are quantified for the case of e+e− collisions at 350 GeV center-of-mass energy and 1 ab−1 itegrated luminosity. The Standard Model Higgsstrahlung production process is used as an example.
