最小超对称标准模型的重整化群研究:无标度模型

Renormalization Group Study of the Minimal Supersymmetric Standard Model : No Scale Models

Pierre Ramond

摘要:

本文给出了超对称软破缺和电弱对称辐射破缺的最小超对称标准模型的部分数值结果。我们施加额外的关系,底部质量=大统一尺度下的τ质量。对于严格的无标度模型的特殊情况下,其中全球超对称性破缺完全来自软高根质量,我们发现,顶部的质量预计将轻于约128 GeV。一个较高的上限约138 GeV的顶部质量的预测,如果底部的质量是在其实验不确定性的下端。

英文摘要:

We present partial numerical results in the Minimal Supersymmetric Standard Model with soft breaking of supersymmetry, and radiative breaking of the electroweak symmetry. We impose the additional relation, bottom mass = tau mass at the GUT scale. For the special case of the strict no-scale model, in which global supersymmetry breaking arises solely from soft gaugino masses, we find that the top mass is expected to be lighter than about 128 GeV. A higher upper bound for the top mass of about 138 GeV is predicted, if the mass of the bottom is at the lower end of its experimental uncertainty.
