Evidence for a Nonplanar Amplituhedron
Zvi Bern, Enrico Herrmann, Sean Litsey +2
The scattering amplitudes of planar N = 4 super-Yang-Mills exhibit a number of remarkable analytic structures, including dual conformal symmetry and logarithmic singularities of in…
On-Shell Recursion Relations for Effective Field Theories
Clifford Cheung, Karol Kampf, Jiri Novotny +2
We derive the first ever on-shell recursion relations for amplitudes in effective field theories. Based solely on factorization and the soft behavior of amplitudes, these recursion…
Local Integrand Representations of All Two-Loop Amplitudes in Planar SYM
Jacob L. Bourjaily, Jaroslav Trnka
We use generalized unitarity at the integrand-level to directly construct local, manifestly dual-conformally invariant formulae for all two-loop scattering amplitudes in planar, ma…
Simple Recursion Relations for General Field Theories
Clifford Cheung, Chia-Hsien Shen, Jaroslav Trnka
On-shell methods offer an alternative definition of quantum field theory at tree-level, replacing Feynman diagrams with recursion relations and interaction vertices with a handful…
