{ital CP}-violating effects in {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital ZH} and their optimization

We consider the possibility of seaching for {ital CP} nonconservation in the process {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital ZH}. The simplest strategy is to measure the forward-backward asymmetry of the {ital Z} boson, a nonzero value of which signals {ital CP} violation. The effects of {ital CP} violation are calculated in the two Higgs doublet model. We show here that a choice of optimal observables can improve the chances of observing the effect. Although the number of events produced is expected not to be large, useful information about {ital CP}-violating parameters can be extracted.
