关于扰动SCFT中标量算子界的一个注记

A Note on Bounds of Scalar Operators in Perturbative SCFTs

Sibo Zheng

摘要:

用微扰的观点讨论了四维超共形场论中标量算符反常维数的界。在Green和Shih最近的工作中,一个涉及这个问题的猜想在非线性光学下得到了验证,我们考虑了对边界的非线性光学修正,这在某些情况下是很重要的,可以分为两种情况,分别是$\mathcal{O}(λ^{4})$或$\mathcal{O}(y^2)$效应占主导地位.在前一种情况下,我们发现该猜想在NNLO处保持不变,而在后一种情况下,由于$\mathcal{O}(y^{2})$引起的零修正,该陈述仍然成立。

英文摘要:

Bounds on anomalous dimensions of scalar operators in 4d superconformal field theory are explored through perturbative viewpoint. Following the recent work of Green and Shih, in which a conjecture involved this issue is verified at the NLO, we consider the NNLO corrections to the bounds, which are important in some situations and can be divided into two cases where $\mathcal{O}(λ^{4})$ or $\mathcal{O}(y^2)$ effects dominate respectively. In the former case, we find that the conjecture is maintained at NNLO, while in the later case, the statement still holds due to the null corrections arising from $\mathcal{O}(y^{2})$.
