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…
Reduction of General One-loop Integrals Using Auxiliary Vector
Bo Feng, Tingfei Li, Hongbin Wang +1
As a key method to deal with loop integrals, Integration-By-Parts (IBP) method can be used to do reduction as well as establish the differential equations for master integrals. How…
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…
