摘要:

本文将$\mathcal{N}=4$超对称的Yang-Mills理论(SYM)中四个超共形应力张量基元的积分关联函数重新表示为二维格点和,该格点和在$SL(2,\mathbb{Z})$ S-对偶下是明显不变的.这个表达式被证明是满足一个新的拉普拉斯方程中的复杂的耦合常数$τ$,涉及的$SU(N)$集成关联函数的$SU(N+1)$和$SU(N-1)$理论。的晶格和精确地再现已知的扰动和非扰动性质的$\mathcal{N}=4$ SYM为任何有限的$N$,以及扩展以前的大- $N$扩展的prostituted属性。

英文摘要:

An integrated correlator of four superconformal stress-tensor primaries of $\mathcal{N}=4$ supersymmetric $SU(N)$ Yang-Mills theory (SYM), originally obtained by localisation, is re-expressed as a two-dimensional lattice sum that is manifestly invariant under $SL(2,\mathbb{Z})$ S-duality. This expression is shown to satisfy a novel Laplace equation in the complex coupling constant $τ$ that relates the $SU(N)$ integrated correlator to those of the $SU(N+1)$ and $SU(N-1)$ theories. The lattice sum is shown to precisely reproduce known perturbative and non-perturbative properties of $\mathcal{N}=4$ SYM for any finite $N$, as well as extending previously conjectured properties of the large-$N$ expansion.
