亚稳秩条件超对称性破缺的手征例子

Metastable Rank-Condition Supersymmetry Breaking in a Chiral Example

Yael Shadmi

摘要:

本文讨论了Intriligator-Seiberg-Shih(ISS)真空到手征模型的推广。我们研究一个例子,一个s-限制理论,详细。在IR中,这个例子减少到两个ISS样的部门,并表现出一个超临界破坏真空与所有的伪模量稳定在原点,与R-对称性未破缺。IR理论从R对称破缺的观点来看是有趣的。这个理论是一个O 'Raifeartaigh模型,所有的电荷都是零或二,但是存在第二个R-带电的赝模,与信使的超电势耦合原则上允许R-对称性破缺。

英文摘要:

We discuss generalizations of Intriligator-Seiberg-Shih (ISS) vacua to chiral models. We study one example, of an s-confining theory, in detail. In the IR, this example reduces to two ISS-like sectors, and exhibits a supersymmetry-breaking vacuum with all pseudo-moduli stabilized at the origin, and with the R-symmetry unbroken. The IR theory is interesting from the point of view of R-symmetry breaking. This theory is an O'Raifeartaigh model with all charges zero or two, but the presence of a second R-charged pseudo-modulus with superpotential couplings to the messengers in principle allows for R-symmetry breaking.
