关于4维秩一N=3超共形场论

On 4d rank-one N=3 superconformal field theories

Takahiro Nishinaka, Yuji Tachikawa

摘要:

研究了秩为1的4维N=3超共形场论的性质,即在真空的模空间上约化为单个向量多重态的场论.我们发现,当k= 1,2,3,4,6时,模空间只能是C^3/Z_k的形式,当k= 1,2时,超对称性自动增强到N=4.此外,我们还确定了关于k的中心荷a和c,并构造了相应的2d手征代数,它们是奇异的N=2超对称W-代数.

英文摘要:

We study the properties of 4d N=3 superconformal field theories whose rank is one, i.e. those that reduce to a single vector multiplet on their moduli space of vacua. We find that the moduli space can only be of the form C^3/Z_k for k=1,2,3,4,6, and that the supersymmetry automatically enhances to N=4 for k=1,2. In addition, we determine the central charges a and c in terms of k, and construct the associated 2d chiral algebras, which turn out to be exotic N=2 supersymmetric W-algebras.
