本文研究维数 $D\ge3$ 的弯曲空间上欧几里得共形场论的若干一般性问题。首先探讨共形平坦空间上标量初级场的算符乘积展开(OPE),扩展文献[Konechny:2026bqg]的结果,给出标量通道中后代场对OPE贡献的一般构造。随后利用Parisini、Skenderis和Withers提出的一般假设,讨论非共形平坦空间上的共形场论(CFT),研究此类空间上三点函数的短程行为,发现需对该假设补充额外修正,以确保局域协变OPE的存在性。
英文摘要
In this paper we consider some general aspects of Euclidean conformal field theories on curved spaces of dimension $D\ge 3$. We first look at the OPE of scalar primary fields on conformally flat spaces. Extending the results of \cite{Konechny:2026bqg}, we give a general construction of the descendants' contributions to the OPE in the scalar channel. We then discuss CFTs on non-conformally flat spaces in the ambient space formalism. We investigate the short-distance behaviour of three-point functions on such spaces using the general ansatz proposed by Parisini, Skenderis, and Withers \cite{Parisini:2022wkb, Parisini:2023nbd}. We find that some additional corrections need to be added to the ansatz to ensure the existence of a local covariant OPE.
