ABJM amplitudes and the positive orthogonal grassmannian
Yu-tin Huang, CongKao Wen
A remarkable connection between perturbative scattering amplitudes of four-dimensional planar SYM, and the stratification of the positive grassmannian, was revealed in the seminal…
Scattering Amplitudes
Henriette Elvang, Yu-tin Huang
The purpose of this review is to bridge the gap between a standard course in quantum field theory and recent fascinating developments in the studies of on-shell scattering amplitud…
On Three-Algebra and Bi-Fundamental Matter Amplitudes and Integrability of Supergravity
Yu-tin Huang, Henrik Johansson, Sangmin Lee
We explore tree-level amplitude relations for SU(N)xSU(M) bi-fundamental matter theories. Embedding the group-theory structure in a Lie three-algebra, we derive Kleiss-Kuijf-like r…
Consistency conditions from generalized-unitarity
Yu-tin Huang, David McGady
In the modern on-shell approach, the perturbative S-matrix is constructed iteratively using on-shell building blocks with manifest unitarity. As only gauge invariant quantities ent…
Color-Kinematics Duality for Pure Yang-Mills and Gravity at One and Two Loops
Zvi Bern, Scott Davies, Tristan Dennen +2
We provide evidence in favor of the conjectured duality between color and kinematics for the case of nonsupersymmetric pure Yang-Mills amplitudes by constructing a form of the one-…
