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…
On the exactness of soft theorems
Andrea L. Guerrieri, Yu-tin Huang, Zhi-Zhong Li +1
Soft behaviours of S-matrix for massless theories reflect the underlying symmetry principle that enforces its masslessness. As an expansion in soft momenta, sub-leading soft theore…
