Infinite Soft Theorems from Gauge Symmetry
Zhi-Zhong Li, Hung-Hwa Lin, Shun-Qing Zhang
In this letter we show that the soft behaviour of photons and graviton amplitudes, after projection, can be determined to infinite order in soft expansion via ordinary on-shell gau…

On the Symmetry Foundation of Double Soft Theorems
Zhi-Zhong Li, Hung-Hwa Lin, Shun-Qing Zhang
Double-soft theorems, like its single-soft counterparts, arises from the underlying symmetry principles that constrain the interactions of massless particles. While single soft the…
