标准模型的超对称扩展一般包含CP破坏的额外来源。讨论了在最小超对称标准模型（MSSM）中，如何在一个环上诱导最轻的Higgs玻色子h{sup 0}与轻子的潜在大CP破坏耦合.在MSSM的扩展中，如次极小超对称标准模型（NMSSM），h{sup 0}的CP破坏耦合也被考虑。我们表明如何CP违规可能会被观察到，特别是一个依赖于极化的生产不对称性，在μ子对撞机的背景下，提供了一种手段来访问这种耦合干净。在MSSM中，电子的电偶极矩的现有限制，加上标准的普适性假设，严重限制了任何这样的信号。然而，MSSM的扩展，例如NMSSM，允许CP违反信号高达100{ %}。{版权} {美国物理学会}
Supersymmetric extensions of the standard model generically contain additional sources of CP violation. We discuss how at one loop a potentially large CP violating coupling of the lightest Higgs boson h{sup 0} to leptons is induced in the minimal supersymmetric standard model (MSSM). The CP violating couplings of h{sup 0} in extensions of the MSSM, such as the next-to-minimal supersymmetric standard model (NMSSM) are also considered. We indicate how this CP violation might be observed; in particular a polarization-dependent production asymmetry, in the context of a muon collider, provides a means to access this coupling cleanly. In the MSSM, existing limits on the electric dipole moment of the electron, coupled with standard universality assumptions, severely constrains any such signal. Nevertheless, extensions of the MSSM, such as the NMSSM, allow CP-violating signals as large as 100{percent}. {copyright} {ital 1998} {ital The American Physical Society}
