Landau singularities of the 7-point ziggurat. Part II

Journal of High Energy Physics
We solve the Landau equations to find the singularities of nine three-loop 7-point graphs that arise as relaxations of the graph studied in [22]. Along the way we establish that Y − ∆ equivalence fails for certain branches of solutions to the Landau ...

Global bases for nonplanar loop integrands, generalized unitarity, and the double copy to all loop orders

Journal of High Energy Physics
We introduce a constructive method for defining a global loop-integrand basis for scattering amplitudes, encompassing both planar and nonplanar contributions.

Positive geometries, corolla polynomial and gauge theory amplitudes

Journal of High Energy Physics
Arkani-Hamed, Bai, He and Yan (ABHY) discovered a convex realisation of the associahedron whose combinatorial and geometric structure generates tree-level amplitudes in bi-adjoint scalar theory.
