用BR(μ \to eγ)和BR(μ \to eγ)探讨跷跷板和量规调解量表|U_{e3}|

Probing the Seesaw and Gauge Mediation Scales with BR(μ\to eγ) and |U_{e3}|

Daniel Grossman, Yosef Nir

摘要:

BR(μ \to eγ)上新的MEG界提供了超对称破缺规范介导尺度上最强的上界.如果在未来,这种衰减被MEG观察到,那么调解规模将在一个数量级内,跷跷板规模将受到限制。在这种情况下,普朗克介导的超对称性破缺的贡献可能是不可忽略的,并且不可能用纯粹的跷跷板参数来解释。最近的证据表明,|U_{e3}| ~0.15进一步加强了规范介导的超对称破缺的预言。

英文摘要:

The new MEG bound on BR(μ\to eγ) provides the strongest upper bound on the scale of gauge mediation of supersymmetry breaking. If, in the future, this decay is observed by MEG, the mediation scale will become known to within one order of magnitude, and the seesaw scale will be constrained. In such a case, contributions from Planck mediated supersymmetry breaking are likely to be non-negligible, and an interpretation in terms of purely seesaw parameters will be impossible. The recent evidence for |U_{e3}|~0.15 further sharpens the predictions of gauge mediated supersymmetry breaking.
