陪集共形块与N=2规范理论

Coset conformal blocks and N=2 gauge theories

Niclas Wyllard

摘要:

最近有人提出su(N)_k+su(N)_p/su(N)_{k+p}陪集共形场论应该与R^4/Z_p上的N=2 SU(N)规范理论相关。本文研究了这一提议的各个方面。我们对(N,p)=(2,4)的关系进行了明确的检验,其中陪集的对称代数是所谓的S_3仿费米子代数。即使陪集的对称代数是未知的通用(N,p)模型,我们管理执行非平凡的检查,在一般情况下,通过使用知识的Kac行列式的陪集CFT。我们还发现证据表明,(N,p)模型的共形块应分解成一定的产品的p(N,1)共形块。确切地说,这种结构存在于R^4/Z_p上的瞬子配分函数中。

英文摘要:

It was recently suggested that the su(N)_k+su(N)_p/su(N)_{k+p} coset conformal field theories should be related to N=2 SU(N) gauge theories on R^4/Z_p. In this paper we study various aspects of this proposal. We perform explicit checks of the relation for (N,p)=(2,4), where the symmetry algebra of the coset is the so called S_3 parafermion algebra. Even though the symmetry algebra of the coset is unknown for generic (N,p) models, we manage to perform non-trivial checks in the general case by using knowledge of the Kac determinant of the coset CFT. We also find evidence that the conformal blocks of the (N,p) model should factorise into a certain product of p (N,1) conformal blocks. Precisely this structure is present in the instanton partition function on R^4/Z_p.
