标题： Perturbative Unification of Soft Supersymmetry--Breaking Terms

摘要： 微扰统一软超对称破缺(SSB)参数在规范- yukawa 统一模型中被提出。 该方法可以在任何微扰理论的有限阶次中应用，其核心是在SSB参数中寻找与重整化群不变的关系，这些关系与微扰可重整性一致。 对于基于$SU(5)$的最小规范-yukawa 统一模型，我们发现低能SSB部分包含一个任意参数，即统一的胶粒质量。 在一定的近似下，我们发现该模型预测的超粒子谱与实验数据一致。 显示英文摘要

摘要： Perturbative unification of soft supersymmetry--breaking (SSB) parameters is proposed in Gauge-Yukawa unified models. The method, which can be applied in any finite order in perturbation theory, consists in searching for renormalization group invariant relations among the SSB parameters, which are consistent with perturbative renormalizability. For the minimal Gauge-Yukawa unified model based on $SU(5)$ we find that the low energy SSB sector contains a single arbitrary parameter, the unified gaugino mass. Within a certain approximation we find that the model predicts a superpartner spectrum which is consistent with the experimental data.
