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

We study the production processes $e^+e^-\to H^0_i Z$, $H^0_i H^0_j$ and $H^0_i \nu_e \overline \nu_e$ 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 $M_{H_{2,3}}\la 300$ GeV. This should be detectable at a Next Linear Collider and would provide evidence for scalar-pseudoscalar mixing.
