Generation Function For One-loop Tensor Reduction
Bo Feng
For loop integrals, the reduction is the standard method. Having an efficient way to find reduction coefficients is an important topic in scattering amplitudes. In this paper, we p…
Module Intersection and Uniform Formula for Iterative Reduction of One-loop Integrals
Jiaqi Chen, Bo Feng
In this paper, we develop an iterative sector-level reduction strategy for Feynman integrals, which bases on module intersection in the Baikov representation and auxiliary vector f…
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…
Universal Treatment of Reduction for One-Loop Integrals in Projective Space
Bo Feng, Jianyu Gong, Tingfei Li
Recently a nice work about the understanding of one-loop integrals has been done in [1] using the tricks of the projective space language associated to their Feynman parametrizatio…
PV-Reduction of Sunset Topology with Auxiliary Vector
Bo Feng, Tingfei Li
Passarino-Veltman (PV) reduction method has been proved to be very useful for the computation of general one-loop integrals. However, not much progress has been made when applying…
The noncommutativity of the static and homogeneous limit of the axial chemical potential in chiral magnetic effect
Bo Feng, De-fu Hou, Hai-cang Ren +1
We study the noncommutativity of different orders of zero energy-momentum limit pertaining to the axial chemical potential in the chiral magnetic effect. While this noncommutativit…
