Extended Projection Method for Massive Fermion
Yefan Wang, Zhao Li
Tensor reduction is important for multi-loop amplitude calculation. And the projection method is one of the most popular approaches for tensor reduction. However, projection method…

Direct reduction of multiloop multiscale scattering amplitudes
Yefan Wang, Zhao Li, Najam ul Basat
We propose an alternative approach based on series representation to directly reduce multi-loop multi-scale scattering amplitude into set of freely chosen master integrals. And thi…
