规范中介模型中的SUSY CP问题

SUSY CP Problem in Gauge Mediation Model

Takeo Moroi, Norimi Yokozaki

摘要:

重新考虑了规范中介超对称破缺模型中的超对称CP问题。我们特别注意两个来源的CP破坏阶段的影响没有认真研究之前,一个是GUT关系的GUT质量之间的破缺的影响,由于场responsible的GUT对称性破缺,另一个是超引力效应的超对称性破缺参数,特别是对双线性超对称性破缺希格斯质量项。结果表明,这两种方法都能诱导出电子、中子等较大的电偶极矩,使之与实验界不一致。

英文摘要:

SUSY CP problem in the gauge mediation supersymmetry breaking model is reconsidered. We pay particular attention to two sources of CP violating phases whose effects were not seriously studied before; one is the effect of the breaking of the GUT relation among the gaugino masses due to the field esponsible for the GUT symmetry breaking, and the other is the supergravity effect on the supersymmetry breaking parameters, in particular, on the bi-linear supersymmetry breaking Higgs mass term. We show that both of them can induce too large electric dipole moments of electron, neutron, and so on, to be consistent with the experimental bounds.
