Can Locality, Unitarity, and Hidden Zeros Completely Determine Tree-Level Amplitudes?
Kang Zhou
In this note, we address the question of whether locality, unitarity, and newly discovered hidden zeros can completely determine tree-level amplitudes, from the perspective of soft…

Hidden zeros for higher-derivative YM and GR amplitudes at tree-level
Kang Zhou
We extend the recently discovered phenomenon of hidden zeros to tree amplitudes for Yang-Mills (YM) and general relativity (GR) theories with higher-derivative interactions. This i…

Towards tree Yang-Mills and Yang-Mills-scalar amplitudes with higher-derivative interactions
Kang Zhou, Chang Hu
In our recent works, a new approach for constructing tree amplitudes, based on exploiting soft behaviors, was proposed. In this paper, we extend this approach to effective theories…
