AMFlow 2.0: significant algorithmic and software improvements for Feynman integral evaluation
Rui-Jun Huang, Xiao Liu, Yan-Qing Ma
We present significant improvements to the AMFlow package for the numerical computation of dimensionally regularized Feynman integrals. Several new features are introduced to reduc…

Efficient Computation of One-Loop Feynman Integrals and Fixed-Branch Integrals to High Orders in
Rui-Jun Huang, Dong-Shan Jian, Yan-Qing Ma +2
We propose a novel method, called the dimension-changing transformation (DCT), to compute one-loop Feynman integrals and recently introduced fixed-branch integrals to arbitrary ord…

Tame multi-leg Feynman integrals beyond one loop
Li-Hong Huang, Rui-Jun Huang, Yan-Qing Ma
We introduce a novel structure for Feynman integrals, reformulating them as integrals over a small set of parameters with a fully controllable integrand. The integrand closely rese…
