Effect of CP violating phases on neutral Higgs boson phenomenology in   the MSSM
  In the MSSM with complex SUSY parameters we consider a specific case where the second heaviest Higgs boson H_2 is SM like, while H_1 and H_3 are both strongly mixed states of CP odd and CP even scalar fields. Such a scenario could be probed at a Linear Collider via the mechanism e^+e^-\to H_1H_3.
