坏理论的红外物理学

The Infrared Physics of Bad Theories

Benjamin Assel, Stefano Cremonesi

摘要:

本文利用$N_f$基本理论研究了三维$\mathcal{N}=4$ $U(N)$ SQCD真空的完备模空间,建立在库仑支的代数描述基础上,并从模空间的局部几何推导出任何真空中的低能物理.我们证实了以前的索赔,好的和丑陋的SQCD理论,并表明,坏的理论流到相同的相互作用的不动点作为良好的理论与额外的自由扭曲超多重态。一个Seiberg-like对偶提出的坏理论与$N \le N_f \le 2N-2$排除:假定的对偶理论的真空空间是不同的。然而,这种坏的理论有一个突出的真空,它保留了所有的整体对称性,其红外物理是建议的对偶。最后,我们解释以前的结果,球配分函数和阐明之间的关系,紫外和红外$R$对称性在这个对称真空。

英文摘要:

We study the complete moduli space of vacua of 3d $\mathcal{N}=4$ $U(N)$ SQCD theories with $N_f$ fundamentals, building on the algebraic description of the Coulomb branch, and deduce the low energy physics in any vacuum from the local geometry of the moduli space. We confirm previous claims for good and ugly SQCD theories, and show that bad theories flow to the same interacting fixed points as good theories with additional free twisted hypermultiplets. A Seiberg-like duality proposed for bad theories with $N \le N_f \le 2N-2$ is ruled out: the spaces of vacua of the putative dual theories are different. However such bad theories have a distinguished vacuum, which preserves all the global symmetries, whose infrared physics is that of the proposed dual. We finally explain previous results on sphere partition functions and elucidate the relation between the UV and IR $R$-symmetry in this symmetric vacuum.
