Five-loop Anomalous Dimensions of Cubic Scalar Theory from Operator Product Expansion
Rijun Huang, Qingjun Jin, Yi Li
In this work, we compute the anomalous dimensions of the operator in six-dimensional cubic scalar theory. The renormalization analysis is carried out within the framework of…

On the Seven-loop Renormalization of Gross-Neveu Model
Rijun Huang, Qingjun Jin, Yi Li
The presence of an infinite number of marginal four-fermion operators is a key characteristic of the two-dimensional Gross-Neveu model. In this study, we investigate the structure…

From Operator Product Expansion to Anomalous Dimensions
Rijun Huang, Qingjun Jin, Yi Li
We propose a new method for computing the renormalization functions, which is based on the ideas of operator product expansion and large momentum expansion. In this method, the ren…
