CP-violating ZZh coupling at e+ e- linear colliders -: art. no. 096007

We study the general Higgs-weak-boson coupling with CP violation via the process e(+)e(-)-->f (f) over barh. We categorize the signal channels by the subprocesses of Zh production and ZZ fusion and construct four CP asymmetries by exploiting polarized e(+)e(-) beams. We find complementarity among the subprocesses and the asymmetries to probe the real and imaginary parts of the CP-violating form factor. Certain asymmetries with unpolarized beams can retain significant sensitivity to the coupling. We conclude that at a linear collider with high luminosity, the CP-odd ZZh coupling may be sensitively probed via measurements of the asymmetries.
