An Explicit Expression of Generating Function for One-Loop Tensor Reduction
Chang Hu, Tingfei Li, Jiyuan Shen +1
This work introduces an explicit expression for the generation function for the reduction of an -gon to an -gon. A novel recursive relation of generation function is form…
Reduction with Degenerate Gram matrix for One-loop Integrals
Bo Feng, Chang Hu, Tingfei Li +1
An improved PV-reduction method for one-loop integrals with auxiliary vector has been proposed in \cite{Feng:2021enk,Hu:2021nia}. It has also been shown that the new method is…
One-loop Feynman Integral Reduction by Differential Operators
Chang Hu, Tingfei Li, Xiaodi Li
For loop integrals, the standard method is reduction. A well-known reduction method for one-loop integrals is the Passarino-Veltman reduction. Inspired by the recent paper [1] wher…
Note on solutions of scattering equations
Bo Feng, Chang Hu, Yaobo Zhang
In the CHY-frame for the amplitudes, there are two kinds of singularities we need to deal with. The first one is the pole singularities when the kinematics is not general, such tha…
Boundary Contributions of On-shell Recursion Relations With Multiple-line Deformation
Chang Hu, Xiao-Di Li, Yi Li
On-shell recursion relation has been recognized as a powerful tool for calculating tree level amplitudes in quantum field theory, but it doesn't work well when the residue of the d…
One-loop CHY-Integrand of Bi-adjoint Scalar Theory
Bo Feng, Chang Hu
In this paper, the one-loop CHY-integrands of bi-adjoint scalar theory has been reinvestigated. Differing from previous constructions, we have explicitly removed contributions from…
