A numerical evaluation of planar two-loop helicity amplitudes for a W-boson plus four partons
Heribertus Bayu Hartanto, Simon Badger, Christian Brønnum-Hansen +1
We present the first numerical results for the two-loop helicity amplitudes for the scattering of four partons and a W-boson in QCD. We use a finite field sampling method to reduce…
FiniteFlow: multivariate functional reconstruction using finite fields and dataflow graphs
Tiziano Peraro
Complex algebraic calculations can be performed by reconstructing analytic results from numerical evaluations over finite fields. We describe FiniteFlow, a framework for defining a…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
Local integrands for two-loop QCD amplitudes
Simon Badger, Gustav Mogull, Tiziano Peraro
In this talk we review the recent computation of the five- and six-gluon two-loop amplitudes in Yang-Mills theory using local integrands which make the infrared pole structure mani…
Tensor integrand reduction via Laurent expansion
Valentin Hirschi, Tiziano Peraro
We introduce a new method for the application of one-loop integrand reduction via the Laurent expansion algorithm, as implemented in the public C++ library Ninja. We show how the c…
One-loop triple collinear splitting amplitudes in QCD
Simon Badger, Francesco Buciuni, Tiziano Peraro
We study the factorisation properties of one-loop scattering amplitudes in the triple collinear limit and extract the universal splitting amplitudes for processes initiated by a gl…
