Direct Expression for One-Loop Tensor Reduction with Lorentz Indices via Generating Function
Chang Hu, Yifan Hu, Jiyuan Shen
In recent work, we derived a direct expression for one-loop tensor reduction using generating functions and Feynman parametrization in projective space, avoiding recursive relation…

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…
