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…

Hidden Zeros in Exceptional Field Theories from Double Copy
Yang Li, Diederik Roest, Tonnis ter Veldhuis
It was recently discovered by Arkani-Hamed et al and Cao et al that the colour-ordered scattering amplitudes of Tr, the non-linear sigma model and Yang-Mills-scalar vanish a…
