Note on tree NLSM amplitudes and soft theorems
Kang Zhou, Fang-Stars Wei
We use the universality of single soft behavior, together with the double copy structure, to completely determine the tree amplitudes of non-linear sigma model (NLSM). We first fig…

Expanding single trace YMS amplitudes with gauge invariant coefficients
Fang-Stars Wei, Kang Zhou
In this note, we use the new bottom up method based on soft theorems to construct the expansion of single-trace Yang-Mills-scalar amplitudes recursively. The resulted expansion man…

Tree and -loop fundamental BCJ relations from soft theorems
Fang-Stars Wei, Kang Zhou
We provide a new derivation of the fundamental BCJ relation among double color ordered tree amplitudes of bi-adjoint scalar theory, based on the leading soft theorem for external s…
