Four-loop Anomalous Dimensions of Scalar-QED Theory from Operator Product Expansion
Rijun Huang, Qingjun Jin, Yi Li
We apply the Operator Product Expansion (OPE) algorithm to the renormalization of scalar-QED theory, with a specific focus on the fixed-charge operator . Within the OPE framew…

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…
Wilson Lines and Boundary Operators of BCFW Shifts
Rijun Huang, Qingjun Jin, Yi Li
Boundary operators are gauge invariant operators whose form factors correspond to boundary contributions of BCFW shifts. In gauge theory, the boundary operators contain infinite se…

Motivated by the problem of expanding single-trace tree-level amplitude of Einstein-Yang-Mills theory to the BCJ basis of Yang-Mills amplitudes, we present an alternative expansion…
Permutation in the CHY-Formulation
Rijun Huang, Fei Teng, Bo Feng
The CHY-integrand of bi-adjoint cubic scalar theory is a product of two PT-factors. This pair of PT-factors can be interpreted as defining a permutation. We introduce the cycle rep…
Understanding the Cancelation of Double Poles in the Pfaffian of CHY-formulism
Rijun Huang, Yi-Jian Du, Bo Feng
For a physical field theory, the tree-level amplitudes should possess only single poles. However, when computing amplitudes with Cachazo-He-Yuan (CHY) formulation, individual terms…

In this paper, we provide a thorough study on the expansion of single trace Einstein-Yang-Mills amplitudes into linear combination of color-ordered Yang-Mills amplitudes, from vari…

Bo Feng, Song He, Rijun Huang +1
In this note, we study the -cut representation by combining it with BCFW deformation. As a consequence, the one-loop integrand is expressed in terms of a recursion rel…
Cross-ratio Identities and Higher-order Poles of CHY-integrand
Carlos Cardona, Bo Feng, Humberto Gomez +1
The evaluation of generic Cachazo-He-Yuan(CHY)-integrands is a big challenge and efficient computational methods are in demand for practical evaluation. In this paper, we propose a…

Rijun Huang, Bo Feng, Ming-xing Luo +1
In this paper, we generalize the integration rules for scattering equations to situations where higher-order poles are present. We describe the strategy to deduce the Feynman rules…

Rijun Huang, Qingjun Jin, Bo Feng
The boundary contribution of an amplitude in the BCFW recursion relation can be considered as a form factor involving boundary operator and unshifted particles. At the tree-level,…

Recently, a new construction for complete loop integrands of massless field theories has been proposed, with on-shell tree-level amplitudes delicately incorporated into its algorit…
