Abstract: | In the s-channel Higgs-boson exchange processes, the interference between the amplitudes for CP-even and CP-odd Higgs bosons is sizable, if the helicities of the initial and final particles are properly fixed and if the mass difference
between these bosons is not much larger than their decay widths. We discuss this interference effect in the process . Examining the effect gives us information on the CP-parity for the Higgs bosons and on the sign of the product of the coupling constants for the and vertices. The feasibility of observing the interference effect in future muon colliders is evaluated in the framework of
the minimal supersymmetric extension of the standard model as an example. |
