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…
Iteratively Reduce Auxiliary Scalar Product in Multi-loop Integrals
Jiaqi Chen
In this paper, we construct a uniform formula that can iteratively reduce all auxiliary scalar product numerators of arbitrary multi-loop Feynman integrals. Integrals with such num…
Module Intersection and Uniform Formula for Iterative Reduction of One-loop Integrals
Jiaqi Chen, Bo Feng
In this paper, we develop an iterative sector-level reduction strategy for Feynman integrals, which bases on module intersection in the Baikov representation and auxiliary vector f…
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…
Two-loop infrared singularities in the production of a Higgs boson associated with a top-quark pair
Jiaqi Chen, Chichuan Ma, Guoxing Wang +2
The associated production of a Higgs boson and a top-quark pair is important for probing the Yukawa coupling of the top quark, and calls for better theoretical modeling. In this pa…
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…
Conformal Bach flow
Jiaqi Chen, Peng Lu, Jie Qing
In this article we introduce conformal Bach flow and establish its well-posedness on closed manifolds. We also obtain its backward uniqueness. To give an attempt to study the long-…
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…
