【 摘 要 】

With the use of transverse polarization (TP), a CP-odd and T-odd observable can be constructed when the final-state particles are self-conjugate. In the case of 𝐻 𝑍 production, this observable can be used to probe a certain effective four-point 𝑒+ 𝑒- 𝑍 𝐻 CP-violating coupling, not accessible without TP. Effective CP-violating 𝑍 𝑍 𝐻 coupling does not contribute to this observable. A similar observable in 𝛾 𝑍 production can be used to probe 𝑒+ 𝑒- 𝛾 𝑍 four-point couplings.
