$SO(N)$和$Sp(N)$ $\mathcal{N}=4$ SYM的“t Hooft”扩展

't Hooft expansion of $SO(N)$ and $Sp(N)$ $\mathcal{N}=4$ SYM revisited

Kazumi Okuyama

摘要:

本文研究了规范群为$SO(N)$或$\mathcal{N}=4$的超对称Yang-Mills(SYM)理论的t Hooft展开。我们考虑固定$g_sN_5$的$1/N_5$展开式,其中$g_s$表示体IIB型弦理论在$AdS_5\times\mathbb{RP}^5$上的弦耦合,$N_5$表示通过$\mathbb{RP}^5$的RR 5型通量. $N_5$与$N$不同,这是由于来自O3-平面的RR电荷的偏移。作为一个例子,我们考虑的自由能的$1/N_5$展开的$\mathcal{N}=4$ SYM在$S^4$和$1/2$ BPS圆形威尔逊环的基本表示的$SO(N)$或$Sp(N)$。我们发现$1/N_5$展开式比普通的$1/N$展开式更像“闭弦”。

英文摘要:

We study the 't Hooft expansion of $d=4$ $\mathcal{N}=4$ supersymmetric Yang-Mills (SYM) theory with the gauge group $SO(N)$ or $Sp(N)$. We consider the $1/N_5$ expansion with fixed $g_sN_5$, where $g_s$ denotes the string coupling of bulk type IIB string theory on $AdS_5\times\mathbb{RP}^5$ and $N_5$ refers to the RR 5-form flux through $\mathbb{RP}^5$. $N_5$ differs from $N$ due to a shift coming from the RR charge of O3-plane. As an example, we consider the $1/N_5$ expansion of the free energy of $\mathcal{N}=4$ SYM on $S^4$ and the $1/2$ BPS circular Wilson loops in the fundamental representation of $SO(N)$ or $Sp(N)$. We find that the $1/N_5$ expansion is more "closed string like" than the ordinary $1/N$ expansion.
