超对称线性${\cal N}=4$代数

The ${\cal N}=4$ Supersymmetric Linear $W_{\infty}[λ]$ Algebra

Changhyun Ahn

摘要:

从最近已知的${\cal N}=2$超对称线性$W_{\infty}^{K,K}[λ]$代数(其中$K$是双基本$β\, γ$和$b \, c$鬼系统的基本(或反基本)表示的维数),我们确定了它在$K=2$上的${\cal N}=4$超对称增强.在此基础上构造了${\cal N}=4$应力能张量、第一${\cal N}=4$多重态及其算符乘积展开式。我们证明了在大$(N,k)$ 't Hooft-like极限下,当$λ_{co} \equiv \frac{(N+1)}{(k+N+2)}$不超过两个中心项时,第一个${\cal N}=4$多重态与其自身之间的OPEs与${\cal N}=4$陪集$\frac{SU(N+2)}{SU(N)}$模型中相应的OPEs相同.这两个参数彼此相关,即$λ=\frac{1}{2}\, λ_{co}$。通过考虑${\cal N}=4$超对称线性$W_{\infty}[λ]$代数中的第二、第三和第四重态,我们还给出了其它的运算熵。

英文摘要:

From the recently known ${\cal N}=2$ supersymmetric linear $W_{\infty}^{K,K}[λ]$ algebra where $K$ is the dimension of fundamental (or antifundamental) representation of bifundamental $β\, γ$ and $b \, c$ ghost system, we determine its ${\cal N}=4$ supersymmetric enhancement at $K=2$. We construct the ${\cal N}=4$ stress energy tensor, the first ${\cal N}=4$ multiplet and their operator product expansions (OPEs) in terms of above bifundamentals. We show that the OPEs between the first ${\cal N}=4$ multiplet and itself are the same as the corresponding ones in the ${\cal N}=4$ coset $\frac{SU(N+2)}{SU(N)}$ model under the large $(N,k)$ 't Hooft-like limit with fixed $λ_{co} \equiv \frac{(N+1)}{(k+N+2)}$, up to two central terms. The two parameters are related to each other $λ=\frac{1}{2}\, λ_{co}$. We also provide other OPEs by considering the second, the third and the fourth ${\cal N}=4$ multiplets in the ${\cal N}=4$ supersymmetric linear $W_{\infty}[λ]$ algebra.
