Description
Transverse polarization of electron and positron beams can be useful because it
permits the use of azimuthal asymmetries even when the final state consists of two
particles. It is found that with the use of transverse polarization, a CP-odd and
T-odd observable can be constructed when the final-state particles are
self-conjugate. In the case of HZ production, this observable can be used to probe a
certain effective four-point e+e-ZH CP-violating coupling, which is not accessible
without transverse polarization. Effective CP-violating ZZH coupling does not
contribute to this observable. A similar observable for the case of gammaZ production
can be used to probe certain effective CP-violating gammaZV (V= gamma, Z) or
e+e-gammaZ four-point couplings.
