大R电荷引起的对称性破缺

Symmetry breaking caused by large R-charge

Akinori Tanaka, Akio Tomiya, Takuya Shimotani

摘要:

利用基于局域化方法的超对称规范理论的精确结果,讨论了通过细谷机制的规范对称性破缺。我们利用S^2 × S^1欧氏空间的理论,研究了威尔逊线相位的有效势如何通过运行虚化学势而变化。为了打破对称性,我们发现大的R-电荷是必要的。在如此大的R-电荷下,我们研究了该理论的相结构。此外,我们还观察到,当我们取R-荷时,弯曲空间的有限尺寸效应并不是很大。

英文摘要:

We discuss the gauge symmetry breaking via the Hosotani mechanism by using exact results on supersymmetric gauge theories based on the localization method. We use the theories on S^2 x S^1 Euclidean space, and study how the effective potential for the Wilson line phase varies by running an imaginary chemical potential. In order to break the symmetry, we find that large R-charge is necessary. With such large R-charge, we study the phase structure of the theory. In addition, we observed that a finite size effect on our curved space when we take R-charge is not so large.
