Query: Resonant CP-Violating Scalar--Pseudoscalar Transitions at mu+ mu-
  Colliders   A mu+ mu- collider is an appealing machine to probe resonant CP-violating
transitions of a CP-even Higgs particle into the Z boson or into another CP-odd
Higgs scalar. These phenomena are studied within a manifestly gauge-invariant
approach implemented by the pinch technique. The CP invariance of an extended
Higgs sector motivated by supersymmetric E_6 models is assumed to be broken
radiatively by the presence of heavy Majorana fermions. CP violation
originating from Higgs-Z mixing is found to be very modest, whereas CP-number
violating transitions involving Higgs scalars only can be resonantly enhanced
up to order of unity.
