论文摘要
时空尺寸的关键$ o（n）$ cft $ 2 <d <4 $是共形场理论的最重要例子之一，伊辛·cft（Ising CFT）为$ n = 1 $，$ 2 \ leq d <4 $，是一个著名的特殊情况。除了众多的物理应用外，它经常用作基于共形对称性的新方法和技术的具体测试地面。在扰动限制中 - $ 4- \ varepsilon $扩展，大型$ n $扩展和$ 2+\tildeε$扩展 - 多年来已经计算了许多共形数据。在本报告中，我们概述了关键的$ o（n）$ CFT，包括一些研究它的方法，并提供了大量的保形数据。从文献中提取的数据，并通过辅助数据文件提供了许多其他计算$ \ varepsilon $异常维度的计算。
The critical $O(N)$ CFT in spacetime dimensions $2 < d < 4$ is one of the most important examples of a conformal field theory, with the Ising CFT at $N=1$, $2 \leq d < 4$, as a notable special case. Apart from numerous physical applications, it serves frequently as a concrete testing ground for new approaches and techniques based on conformal symmetry. In the perturbative limits - the $4-\varepsilon$ expansion, the large $N$ expansion and the $2+\tildeε$ expansion - a lot of conformal data have been computed over the years. In this report, we give an overview of the critical $O(N)$ CFT, including some methods to study it, and present a large collection of conformal data. The data, extracted from the literature and supplemented by many additional computations of order $\varepsilon$ anomalous dimensions, are made available through an ancillary data file.
