摘要：
The possibility of producing light pseudoscalar Higgs bosons, which naturally appear in extensions of the standard model, is analyzed for Z decays. If kinematically allowed, these particles can be produced copiously in association with scalar Higgs bosons in the minimal SUSY extension. Bremsstrahlung off heavy fermions, however, provides access to these particles also in large areas of the parameter space in less constrained models. We discuss the rates and signatures in Z decays and we estimate the range of masses and mixing angles that can be explored at LEP.
