Simeon Hellerman, Shunsuke Maeda, Domenico Orlando, Susanne Reffert, Masataka Watanabe

摘要:

在大量子数展开的框架下,研究了四种味的$SU(2)$ $\mathcal{N}=2$ SQCD中库仑分支算符的相邻算符对的比值.利用顺序的顺序S-对偶不变性的大R-电荷的扩展,我们从头计算的依赖性领先的大$\mathcal{J}$行为的边际耦合$τ$,我们发现很好的协议与本地化的数值估计。

英文摘要:

We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $\mathcal{N}=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of the large-R-charge expansion we compute ab initio the dependence of the leading large-$\mathcal{J}$ behavior on the marginal coupling $τ$ and we find excellent agreement with numerical estimates from localization.
