On an approach to canonicalizing elliptic Feynman integrals
Jiaqi Chen, Li Lin Yang, Yiyang Zhang
We present generic expressions for the integrands of canonical bases under maximal cut in elliptic Feynman integral families with multiple kinematic scales. Such integrals frequent…

A three-body form factor at sub-leading power in the high-energy limit: planar contributions
Yishuai Guo, Zhi-Feng Liu, Mingming Lu +2
We consider two-loop planar contributions to a three-body form factor at the next-to-leading power in the high-energy limit, where the masses of external particles are much smaller…

Intersection theory, relative cohomology and the Feynman parametrization
Mingming Lu, Ziwen Wang, Li Lin Yang
We present a novel approach for loop integral reduction in the Feynman parametrization using intersection theory and relative cohomology. In this framework, Feynman integrals corre…
