Self-Dual Gravity and Color-Kinematics Duality in

A Lipstein, S Nagy - Physical Review Letters, 2023 - APS
We show that self-dual gravity in Euclidean four-dimensional anti–de Sitter space (AdS 4)
can be described by a scalar field with a cubic interaction written in terms of a deformed …

Gauge independent kinematic algebra of self-dual Yang-Mills theory

R Bonezzi, F Díaz-Jaramillo, S Nagy - Physical Review D, 2023 - APS
The double-copy program relies crucially on the so-called color-kinematics duality which, in
turn, is widely believed to descend from a kinematic algebra possessed by gauge theories …

Infinite-dimensional hierarchy of recursive extensions for all subn-leading soft effects in Yang-Mills

S Nagy, J Peraza, G Pizzolo - Journal of High Energy Physics, 2024 - Springer
