Spacelike-Collinear Scattering by the Method of Regions
Wen Chen, Einan Gardi, Rourou Ma +3
We study the spacelike-collinear limit of gauge-theory scattering amplitudes using the Method of Regions. The corresponding splitting amplitude violates strict collinear factorisat…
An Improvement of AmpRed: Analytic Continuation of Complex Integrals
Wen Chen
The AmpRed package has been updated with an improved method for analytic continuation of complex integrals. Compared to the previous version, the new implementation significantly e…
Semi-automatic Calculations of Multi-loop Feynman Amplitudes with AmpRed
Wen Chen
We present a Mathematica package AmpRed for the semi-automatic calculations of multi-loop Feynman amplitudes with high efficiency and precision. AmpRed implements the methods of in…
Unregulated Divergences of Feynman Integrals
Wen Chen
Feynman integrals can be expanded asymptotically with respect to some small parameters at the integrand level, a technique known as the expansion by regions. A naive expansion by r…
Soft Theorem to Three Loops in QCD and Super Yang-Mills Theory
Wen Chen, Ming-xing Luo, Tong-Zhi Yang +1
The soft theorem states that scattering amplitude in gauge theory with a soft gauge-boson emission can be factorized into a hard scattering amplitude and a soft factor. In this pap…
Reduction of Feynman Integrals in the Parametric Representation II: Reduction of Tensor Integrals
Wen Chen
In a recent paper by the author (Chen in JHEP 02:115, 2020), the reduction of Feynman integrals in the parametric representation was considered. Tensor integrals were directly para…
