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…
Intersection theory rules symbology
Jiaqi Chen, Bo Feng, Li Lin Yang
We propose a novel method to determine the structure of symbols for any family of polylogarithmic Feynman integrals. Using the d log-bases and simple formulas for the leading order…
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…
Alphabet of one-loop Feynman integrals
Jiaqi Chen, Chichuan Ma, Li Lin Yang
In this paper, we present the universal structure of the alphabet of one-loop Feynman integrals. The letters in the alphabet are calculated using the Baikov representation with cut…
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…
