Solving arbitrary one-loop reduction via generating function
Tingfei Li, Yuekai Song, Liang Zhang
Recently, the concept of generating function has been employed in one-loop reduction. For one-loop integrals encompassing arbitrary tensor ranks and higher-pole contributions, the…
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…
Nontrivial One-loop Recursive Reduction Relation
Tingfei Li
In arXiv:2204.03190, we proposed a universal method to reduce one-loop integrals with both tensor structure and higher-power propagators. But the method is quite redundant as it do…
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…
