在S-限制理论中寻找动力学超对称破缺

Hunting for Dynamical Supersymmetry Breaking in Theories That S-confine

Tongyan Lin, John D. Mason, Aqil Sajjad

摘要:

s-限制理论是一类具有红外动力学的超对称规范理论,已被广泛理解。扰动这样的理论可以引起动力学超对称性破缺。我们用一个三线性算符扰动10个SU(N)s-限制规范理论中的两个,实现了动力学超对称破缺的简单模型。这些例子都有局部稳定的真空自发超对称破缺。第一种是SU(5),具有两代(由一个反对称张量和一个反基本张量组成)和两种味道。第二个是SU(5),有三代。前一种真空的性质是可计算的,而后一种真空的性质是不可计算的。我们简要地讨论了其他SU(N)模型。

英文摘要:

The s-confining theories are a class of supersymmetric gauge theories with infrared dynamics which are well-understood. Perturbing such theories can give rise to dynamical supersymmetry breaking. We realize simple models of dynamical supersymmetry breaking by perturbing two of the 10 SU(N) s-confining gauge theories by a single trilinear operator. These examples have locally stable vacua with spontaneous supersymmetry breaking. The first is SU(5) with two generations (consisting of an antisymmetric tensor and an antifundamental) plus two flavors. The second is SU(5) with three generations. The properties of the former vacuum are calculable while those of the latter vacuum are not. We briefly discuss the other SU(N) models.
