Using decay angle correlations to detect CP violation in the neutral Higgs sector

We demonstrate that decay angle correlations in \taum\taup and t\anti t decay modes could allow a determination of whether or not a neutral Higgs boson is a CP eigenstate. Sensitivity of the correlations is illustrated in the case of the \epem\rta Z \hn and \mupmum\rta \hn production processes for a two-doublet Higgs model with CP-violating neutral sector. A very useful technique for minimizing `depolarization-factor' suppressions of the correlations in the t\anti t mode is introduced.
