    • Abstract

       

      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 $\gamma Z$ production can be used to probe $e^{+} e^{-} \gamma Z$ four-point couplings.
