AI总结:

本文通过将6d (2,0)理论的受保护子扇区映射为$\mathcal{W}$-代数截断,利用全纯自举求解混合四点函数,提取OPE系数并验证与M理论散射修正一致。

摘要:

类型为 $\mathfrak{g}$ 的 6d (2,0) SCFT 具有受保护子扇区,arxiv:1404.1079 中猜想这些子扇区可由 $\mathcal{W}_\mathfrak{g}$ 代数描述。我们写出 6d (2,0) 理论中 1/2-BPS 算子 $S_{k_i}$ 的混合四点函数 $\langle S_{k_1} S_{k_2}S_{k_3}S_{k_4}\rangle$ 的交叉方程,并详细说明某种扭曲如何将该系统简化为 2d 亚纯 CFT 多关联子自举问题。我们将类型 $\mathfrak{g} = \{A_{N-1},D_N\}$ 的相关 6d (2,0) $\mathcal{W}$-代数识别为 $\mathcal{W}_{1+\infty}$ 的截断,并使用 $\texttt{OPEdefs}$ 和 arxiv:1503.07111 的全纯自举方法求解其结构常数的 OPE 结合性条件。由此,我们求解了涉及所有 $S_{k_i}$ 直至 $\{k_i\}=4$ 的扭曲 6d 四点关联子 $\mathcal{F}_{k_1k_2k_3k_4}$ 的多关联子自举,并提取了 6d OPE 系数的闭式表达式。我们描述了我们的 CFT 数据对 (2,0) 理论共形 Regge 轨迹的影响,最后证明了我们的结果与 $AdS_7\times S^4/\mathbb{Z}_\mathfrak{o}$ 上 M 理论中引力子散射的受保护高阶导数修正的一致性。

英文摘要:

6d (2,0) SCFTs of type $\mathfrak{g}$ have protected subsectors that were conjectured in arxiv:1404.1079 to be captured by $\mathcal{W}_\mathfrak{g}$ algebras. We write down the crossing equations for mixed four-point functions $\langle S_{k_1} S_{k_2}S_{k_3}S_{k_4}\rangle$ of 1/2-BPS operators $S_{k_i}$ in 6d (2,0) theories and detail how a certain twist reduces this system to a 2d meromorphic CFT multi-correlator bootstrap problem. We identify the relevant 6d (2,0) $\mathcal{W}$-algebras of type $\mathfrak{g} = \{A_{N-1},D_N\}$ as truncations of $\mathcal{W}_{1+\infty}$ and solve OPE associativity conditions for their structure constants, both using $\texttt{OPEdefs}$ and the holomorphic bootstrap of arxiv:1503.07111. With this, we solve the multi-correlator bootstrap for twisted 6d four-point correlators $\mathcal{F}_{k_1k_2k_3k_4}$ involving all $S_{k_i}$ up to $\{k_i\}=4$ and extract closed-form expressions for 6d OPE coefficients. We describe the implications of our CFT data on conformal Regge trajectories of the (2,0) theories and finally, demonstrate the consistency of our results with protected higher-derivative corrections to graviton scattering in M-theory on $AdS_7\times S^4/\mathbb{Z}_\mathfrak{o}$.
