摘要:

提出了一种新的圆紧化6d $(D_{N+4}, D_{N+4})$最小共形物质理论的5d描述,它可以用具有$N_f=2N+8$味和一个张量多重态的6d $\mathcal{N}=(1,0)$ $Sp(N)$规范理论来逼近.紧化6d理论的膜结构,我们得到了5d $\mathcal{N}=1$ $SU(N+2)$理论的5膜Tao图,该图具有$2N+8$的消失的Chern-Simons能级。我们猜想,6d理论是恢复作为UV不动点的5d理论。通过对7-膜单值性的分析,我们证明了这个5d理论的全局对称性与6d理论的全局对称性是$SO(4N+16)$.利用陶图,我们还发现瞬子逸度正好由圆半径决定。通过在这个5d理论中解耦味道,我们可以得到所有的5d $SU(N+2)$规范理论的各种Chern-Simons水平和相应的增强的整体对称性在5d UV固定点。

英文摘要:

We propose a new 5d description of the circle-compactified 6d $(D_{N+4}, D_{N+4})$ minimal conformal matter theory which can be approached by the 6d $\mathcal{N}=(1,0)$ $Sp(N)$ gauge theory with $N_f=2N+8$ flavors and one tensor multiplet. Compactifying the brane set-up for the 6d theory, we arrive at a 5-brane Tao diagram for 5d $\mathcal{N}=1$ $SU(N+2)$ theory of the vanishing Chern-Simons level with $2N+8$ flavors. We conjecture that the 6d theory is recovered as the UV fixed point of this 5d theory. We show that the global symmetry of this 5d theory is $SO(4N+16)$ identical to that of the 6d theory by analyzing the 7-brane monodromy. By using the Tao diagram, we also find the instanton fugacity is exactly given by the circle radius. By decoupling flavors in this 5d theory, one can obtain all the 5d $SU(N+2)$ gauge theories of various Chern-Simons levels and corresponding enhanced global symmetries at the 5d UV fixed point.
