Unified web for expansions of amplitudes
Kang Zhou
In this paper, we demonstrate that using differential operators one can construct the complete unified web for expansions of amplitudes for a wide range of theories. We first re-de…

Expansion of tree amplitudes for EM and other theories
Shi-Qian Hu, Kang Zhou
The expansions of tree-level amplitudes for one theory into amplitudes for another theory, which have been studied in various recent literatures, exhibit hidden connections between…

Expansion of Einstein-Yang-Mills theory by Differential Operators
Bo Feng, Xiaodi Li, Kang Zhou
The factorization form of the integrands in the Cachazo-He-Yuan (CHY) formalism makes the generalized Kawai-Lewellen-Tye (KLT) relations manifest, thus amplitudes of one theory can…
