We calculate interaction constants for the contributions from \PT-oddscalar-pseudoscalar and tensor-pseudotensor operators to the electric dipolemoment of ${}^{129}$Xe, for the first time in case of the former, usingrelativistic many-body theory including the effects of dynamical electroncorrelations. These interaction constants are necessary ingredients to relatingthe corresponding measurements to fundamental parameters in models of physicsbeyond the Standard Model. We obtain $\alpha_{C_S} = \left( 0.71 \pm 0.18\right) [10^{-23}\, e~\text{cm}]$ and $\alpha_{C_T}= \left( 0.520 \pm 0.049\right) [10^{-20}\, \left<\Sigma\right>_{\text{Xe}}\, e~\text{cm}]$,respectively. We apply our results to test a phenomenological relation betweenthe two quantities, commonly used in the literature, and discuss their presentand future phenomenological impact.
