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…

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…
Trivalent Feynman Diagrams as a Flag

By identifying each standard flag with a trivalent Feynman diagram, the corresponding propagators can be read directly from the flag itself. Within the flag representation, the kin…
Symbol letters of Feynman integrals from Gram determinants
