Ω变形3d N=4规范理论中库仑分支算符的SUSY局域化

SUSY localization for Coulomb branch operators in omega-deformed 3d N=4 gauge theories

Takuya Okuda, Yutaka Yoshida

摘要:

我们在具有$Ω$形变的$\mathbb{R}^3$中对三维$\mathcal{N}=4$规范理论的库仑分支算符进行了超对称定域。对于期望值不涉及非微扰修正的dressed算子,我们的计算再现了所谓的阿贝尔化过程的结果。对于$U(N)$规范理论中的其他算符的期望值和多重算符的关联函数,我们利用构造的矩阵模型计算了由微扰气泡引起的非微扰修正.我们与本地化的结果,在数学文献中讨论的代数结构,并指出了一个类似的关系线运营商在4D $\mathcal{N}=2$规范理论。对于三维$U(N)$(正)规范理论,我们证明了穿墙与算符序之间的直接对应。

英文摘要:

We perform SUSY localization for Coulomb branch operators of 3d $\mathcal{N}=4$ gauge theories in $\mathbb{R}^3$ with $Ω$-deformation. For the dressed monopole operators whose expectation values do not involve non-perturbative corrections, our computations reproduce the results of the so-called abelianization procedure. For the expectation values of other operators and the correlation functions of multiple operators in $U(N)$ gauge theories, we compute the non-perturbative corrections due to monopole bubbling using matrix models obtained by brane construction. We relate the results of localization to algebraic structures discussed in the mathematical literature, and also point out a similar relation for line operators in 4d $\mathcal{N}=2$ gauge theories. For $U(N)$ (quiver) gauge theories in 3d we demonstrate a direct correspondence between wall-crossing and the ordering of operators.
