Spacelike-Collinear Scattering by the Method of Regions
Wen Chen, Einan Gardi, Rourou Ma +3
The paper analyses the spacelike‑collinear limit of gauge‑theory scattering amplitudes using the Method of Regions, identifying a hidden soft‑Glauber region that generates kinemati…
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…
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…
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…
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…
