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…
Local finiteness for real-virtual corrections to electroweak production in partonic collisions
Charalampos Anastasiou, Julia Karlen, Yao Ma +1
We present a local subtraction scheme that enables the combined integration of loop momenta and the final-state parton phase space in real-virtual NNLO QCD corrections to cross sec…
All-order prescription for facet regions in massless wide-angle scattering
Yao Ma
We take a step toward answering a long-standing question in the asymptotic expansion of Feynman integrals: how to systematically determine the regions in the Expansion-by-Regions t…
Identifying regions for asymptotic expansions of amplitudes: fundamentals and recent advances
Yao Ma
This review paper discusses the identification of regions, a crucial first step in applying the "method-of-regions" technique. A systematic approach based on Newton polytope geomet…
