N=2 SYM中的非超对称亚稳介电常数软断裂到N=1

Non Supersymmetric Metastable Vacua in N=2 SYM Softly Broken to N=1

Georgios Pastras

摘要:

在四维N=2的规范理论中,我们发现了非超对称的亚稳真空。首先我们研究最简单的情形,即无味SU(2)规范理论。我们研究了亚稳真空的光谱和寿命以及该模型在紫外完备理论中的可能嵌入。然后我们考虑更大的规范群理论与风味。我们证明了当我们将它们软破为N=1时,在其模空间的特定子流形上诱导的势与低秩规范理论中的势相同。然后,我们表明,当我们离开这个子流形时,势增加,使我们能够在可以简化为SU(2)情况的理论中在它们上构造亚稳真空。

英文摘要:

We find non-supersymmetric metastable vacua in four dimensional N=2 gauge theories softly broken to N=1 by a superpotential term. First we study the simplest case, namely the SU(2) gauge theory without flavors. We study the spectrum and lifetime of the metastable vacuum and possible embeddings of the model in UV complete theories. Then we consider larger gauge group theories with flavors. We show that when we softly break them to N=1, the potential induced on specific submanifolds of their moduli space is identical to the potential in lower rank gauge theories. Then we show that the potential increases when we move away from this submanifold, allowing us to construct metastable vacua on them in the theories that can be reduced to the SU(2) case.
