One-loop Feynman Integral Reduction by Differential Operators
Chang Hu, Tingfei Li, Xiaodi Li
For loop integrals, the standard method is reduction. A well-known reduction method for one-loop integrals is the Passarino-Veltman reduction. Inspired by the recent paper [1] wher…
Analytic Tadpole Coefficients of One-loop Integrals
Bo Feng, Tingfei Li, Xiaodi Li
One remaining problem of unitarity cut method for one-loop integral reduction is that tadpole coefficients can not be straightforward obtained through this way. In this paper, we r…
Leading singularities in Baikov representation and Feynman integrals with uniform transcendental weight
Christoph Dlapa, Xiaodi Li, Yang Zhang
We provide a leading singularity analysis protocol in Baikov representation, for the searching of Feynman integrals with uniform transcendental (UT) weight. This approach is powere…
Expansion of Einstein-Yang-Mills theory by Differential Operators
Bo Feng, Xiaodi Li, Kang Zhou
The factorization form of the integrands in the Cachazo-He-Yuan (CHY) formalism makes the generalized Kawai-Lewellen-Tye (KLT) relations manifest, thus amplitudes of one theory can…
