One-loop calculations in the chirality-flow formalism
Andrew Lifson, Simon Plätzer, Malin Sjodahl
In a few recent papers we introduced the chirality-flow formalism, which was shown to make calculations of tree-level Feynman diagrams simple and transparent. Chirality flow, which…
Wigner 6j symbols for SU(N): Symbols with at least two quark-lines
Judith Alcock-Zeilinger, Stefan Keppeler, Simon Plätzer +1
We study a class of SU(N) Wigner 6j symbols involving two fundamental representations, and derive explicit formulae for all 6j symbols in this class. Our formulae express the 6j sy…
Amplitude Factorization in the Electroweak Standard Model
Simon Plätzer, Malin Sjodahl
We lay out the basis of factorization at the amplitude level for processes involving the entire Standard Model. The factorization appears in a generalized eikonal approximation in…
Automating scattering amplitudes with chirality flow
Andrew Lifson, Malin Sjodahl, Zenny Wettersten
Recently we introduced the chirality-flow formalism, a method which builds on the spinor-helicity formalism and is inspired by the color-flow idea in QCD. With this formalism, Feyn…
The chirality-flow formalism for the standard model
Joakim Alnefjord, Andrew Lifson, Christian Reuschle +1
In a recent paper we introduced the chirality-flow formalism, a method for simple and transparent calculations of Feynman diagrams based on the left- and right-chiral $\mathrm{sl}(…
