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…
Multi-trace YMS amplitudes from soft behavior
Yi-Jian Du, Kang Zhou
Tree level multi-trace Yang-Mills-scalar (YMS) amplitudes have been shown to satisfy a recursive expansion formula, which expresses any YMS amplitude by those with fewer gluons and…
Recursive construction for expansions of tree Yang-Mills amplitudes from soft theorem
Chang Hu, Kang Zhou
In this paper, we have introduced a fundamentally different approach, based on a bottom-up methodology, to expand tree-level Yang-Mills (YM) amplitudes into Yang-Mills-scalar (YMS)…
