γ形变N=4 SYM的基态谱研究

Exploring the ground state spectrum of gamma-deformed N=4 SYM

Fedor Levkovich-Maslyuk, Michelangelo Preti

摘要:

我们研究了平面N=4超杨-米尔斯理论的伽玛变形,它打破了所有的超对称性,但预计将保持可积性的模型。我们专注于运营商Tr $(ϕ_1ϕ_1)$建立从两个标量,其可积性的描述已受到质疑之前,由于双迹计数项的贡献。我们表明,尽管有这些微妙的影响,基于可积性的量子谱曲线(QSC)框架完美地适用于这种状态,特别是再现了已知的1-循环预测。这解决了早期关于该算子的争议,并提供了进一步的证据表明γ变形模型至少在平面极限下是可积的CFT。我们使用QSC计算的前5弱耦合的反常尺寸解析,匹配已知的结果在渔网限制,也计算它的数值从弱到强耦合的所有方式。我们还利用这些数据来提取一个新的系数的双迹算子耦合的beta函数。

英文摘要:

We study the gamma-deformation of the planar N=4 super Yang-Mills theory which breaks all supersymmetries but is expected to preserve integrability of the model. We focus on the operator Tr$(ϕ_1ϕ_1)$ built from two scalars, whose integrability description has been questioned before due to contributions from double-trace counterterms. We show that despite these subtle effects, the integrability-based Quantum Spectral Curve (QSC) framework works perfectly for this state and in particular reproduces the known 1-loop prediction. This resolves an earlier controversy concerning this operator and provides further evidence that the gamma-deformed model is an integrable CFT at least in the planar limit. We use the QSC to compute the first 5 weak coupling orders of the anomalous dimension analytically, matching known results in the fishnet limit, and also compute it numerically all the way from weak to strong coupling. We also utilize this data to extract a new coefficient of the beta function of the double-trace operator couplings.
