CP-violating ZZh Coupling at e+e- Linear Colliders | | T. Han

21 Nov 2000 | | Journal: | Phys.Rev. D63 (2001) 096007 | | Subject: | hep-ph hep-ex | | Abstract: | We study the general Higgs-weak boson coupling with CP-violation via the process e+e- -> f ar f h. We categorize the signal channels by sub-processes Zh production and ZZ fusion and construct four CP asymmetries by exploiting polarized e+e- beams. We find complementarity among the sub-processes 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. | | Source: | arXiv, hep-ph/0011271 | | Services: | Forum | Review | PDF | Favorites | |
