Real time lattice correlation functions from differential equations
Federico Gasparotto, Stefan Weinzierl, Xiaofeng Xu
We report on an exact calculation of lattice correlation functions on a finite four-dimensional lattice with either Euclidean or Minkowskian signature. The lattice correlation func…
Baikov representations, intersection theory, and canonical Feynman integrals
Jiaqi Chen, Xuhang Jiang, Chichuan Ma +2
The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases…
Constructing Canonical Feynman Integrals with Intersection Theory
Jiaqi Chen, Xuhang Jiang, Xiaofeng Xu +1
Canonical Feynman integrals are of great interest in the study of scattering amplitudes at the multi-loop level. We propose to construct -form integrals of the hypergeometri…
