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…
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 and interpret the regions in the Expansio…
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…
Splitting amplitudes at NLO in QCD
Xin Guan, Franz Herzog, Yao Ma +2
In the limit where partons become collinear to each other, scattering amplitudes factorize into a product of universal, process-independent building blocks and scattering amplitude…
Revealing Hidden Regions in Wide-Angle and Forward Scattering
Einan Gardi, Franz Herzog, Stephen Jones +1
We discuss a class of Feynman Integrals containing hidden regions that are not straightforwardly identified using the geometric, or Newton polytope, approach to the method of regio…
Dissecting polytopes: Landau singularities and asymptotic expansions in scattering
Einan Gardi, Franz Herzog, Stephen Jones +1
Parametric representations of Feynman integrals have a key property: many, frequently all, of the Landau singularities appear as endpoint divergences. This leads to a geometric int…
Identifying regions in wide-angle scattering via graph-theoretical approaches
Yao Ma
The method of regions, which provides a systematic approach for computing Feynman integrals involving multiple kinematic scales, proposes that a Feynman integral can be approximate…
Single-soft emissions for amplitudes with two colored particles at three loops
Franz Herzog, Yao Ma, Bernhard Mistlberger +1
We compute the three-loop correction to the universal single-soft emission current for the case of scattering amplitudes with two additional color-charged partons. We present resul…
