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…
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…
