复线性有效理论与超对称破缺

Complex Linear Effective Theory and Supersymmetry Breaking Vacua

Fotis Farakos, Rikard von Unge

摘要:

本文计算了耦合到有质量U(1)矢量多重态的无质量和有质量复线性超场的低能有效作用量。我们的计算包括超空间高阶导数修正,因此超出了之前的结果。在超空间高阶导数中,我们发现导致辅助场势变形和可能破坏超对称性的项也产生了。我们证明了超对称破缺真空只有在高阶项之间存在一个层次结构时才是可信的。重整化群分析表明,一般来说,量子修正并不产生一个层次结构。

英文摘要:

We calculate the low energy effective action of massless and massive complex linear superfields coupled to a massive U(1) vector multiplet. Our calculations include superspace higher derivative corrections and therefore go beyond previous results. Among the superspace higher derivatives we find that terms which lead to a deformation of the auxiliary field potential and may break supersymmetry are also generated. We show that the supersymmetry breaking vacua can only be trusted if there exists a hierarchy between the higher order terms. A renormalization group analysis shows that generically a hierarchy is not generated by the quantum corrections.
