Abstract

We consider a particular two-Higgs-doublet model with spontaneous CP violation, where two neutral Higgses have no definite CP properties and the third one is CP-even. In this model, as the parameter θ of CP violation increases, the masses of the neutral Higgs bosons are drawn towards the mass of the lightest one and the chance of detection of neutral Higgses at an e⁺e^- collider in Z+Higgs, bb+Higgs and tt+Higgs production increases with respect to the CP conserving case.
