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…

-brane Galilean and Carrollian Geometries and Gravities
Eric Bergshoeff, José Figueroa-O'Farrill, Kevin van Helden +3
We study -dimensional -brane Galilean geometries via the intrinsic torsion of their adapted connections. These non-Lorentzian geometries are examples of -structures whose…

Hybrid Goldstone Modes from the Double Copy Bootstrap
Yang Li, Diederik Roest, Tonnis ter Veldhuis
We perform a systematic classification of scalar field theories whose amplitudes admit a double copy formulation and identify two building blocks at 4-point and 13 at 5-point. Usin…
