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…
Unified Geometric Perspective for Spin-1 Systems: Bridging Nematic Director and Majorana Stars
Jiangnan Biguo, Rourou Ma
We present a unified geometric approach for spin-1 systems that connects seemingly distinct geometric representations such as the nematic director, the Cartesian representation and…
Singularity-Free Feynman Integral Bases
Stefano De Angelis, David A. Kosower, Rourou Ma +2
Standard integration-by-parts (IBP) reduction methods typically yield Feynman integral bases where the reduction of some integrals gives rise to coefficients singular as the dimens…
Differential Equations for Energy Correlators in Any Angle
Rourou Ma, Jianyu Gong, Jingwen Lin +3
Energy Correlators (EC) are the simplest IR finite observables, which connect theories and experiments. In this paper, we provide a systematic algorithm to calculate the canonical…
Complete monotonicity of log-functions
Rourou Ma, Julian Weigert
In this article we investigate the property of complete monotonicity within a special family of functions in variables involving logarithms. The main result of…
Performing integration-by-parts reductions using NeatIBP 1.1 + Kira
Zihao Wu, Janko Böhm, Rourou Ma +3
We introduce a new version v1.1 of NeatIBP. In this new version, a Kira interface is included. It allows the user to reduce the integration-by-parts (IBP) identity systems generate…
Two-Loop Spacelike Splitting Amplitude for N=4 Super-Yang-Mills Theory
Johannes Henn, Rourou Ma, Yongqun Xu +3
The study of collinear behavior for gauge theories in the spacelike region is of great phenomenological and theoretical importance. We analytically calculate the two-loop spacelike…
NeatIBP 1.0, A package generating small-size integration-by-parts relations for Feynman integrals
Zihao Wu, Janko Boehm, Rourou Ma +2
In this work, we present the package {\sc NeatIBP}, which automatically generates small-size integration-by-parts (IBP) identities for Feynman integrals. Based on the syzygy and mo…
Four-dimensional differential equations for the leading divergences of dimensionally-regulated loop integrals
Johannes Henn, Rourou Ma, Kai Yan +1
We invent an automated method for computing the divergent part of Feynman integrals in dimensional regularization. Our method exploits simplifications from four-dimensional integra…
A study of Feynman integrals with uniform transcendental weights and the symbology from dual conformal symmetry
Song He, Zhenjie Li, Rourou Ma +3
Multi-loop Feynman integrals are key objects for the high-order correction computations in high energy phenomenology. These integrals with multiple scales, may have complicated sym…
pfd-parallel, a Singular/GPI-Space package for massively parallel multivariate partial fractioning
Dominik Bendle, Janko Boehm, Murray Heymann +6
Multivariate partial fractioning is a powerful tool for simplifying rational function coefficients in scattering amplitude computations. Since current research problems lead to lar…
