Probing scalar-pseudoscalar mixing in the CP violating MSSM at high-energy $e^{+}{e}^{-}$ colliders

We study the production processes $e^{+}{e}^{-}\to H_i^{0}Z$, $H_i^0{H}_j^0$ and $H_i^0{\nu }_e{\bar{\nu }}_e$ in the context of the CP violating MSSM. In a given channel we show that the cross-section for all i (=1,2,3) can be above 0.1 fb provided $M_{H_{2,3}}\text{la}300$ GeV. This should be detectable at a Next Linear Collider and would provide evidence for scalar-pseudoscalar mixing.
