Geometric duality between effective field theories I: scattering amplitudes
Tomas Brauner, Yang Li, Diederik Roest +1
We propose a novel type of duality that connects a sequence of well-known theories with even-multiplicity scalar amplitudes: it relates the Yang-Mills theory coupled to a specific…

Diagrammatic Derivation of Hidden Zeros and Exact Factorisation of Pion Scattering Amplitudes
Yang Li, Tianzhi Wang, Tomáš Brauner +1
Pion scattering amplitudes were recently found to vanish on specific kinematic loci, and to factorise close to these loci into a product of two lower-point amplitudes of an extende…
