From U(1) to E8: soft theorems in supergravity amplitudes
Wei-Ming Chen, Yu-tin Huang, Congkao Wen
It is known that for N=8 supergravity, the double-soft-scalar limit of a n-point amplitude is given by a sum of local SU(8) rotations acting on a (n-2)-point amplitude. For N<8 sup…
New fermionic soft theorems
Wei-Ming Chen, Yu-tin Huang, Congkao Wen
Soft limits of massless S-matrix are known to reflect symmetries of the theory. In particular for theories with Goldstone bosons, the double-soft limit of scalars reveals the coset…
Anomalies without an action
Wei-Ming Chen, Yu-tin Huang, David A. McGady
Modern on-shell methods allow us to construct both the classical and quantum S-matrix for a large class of theories, without utilizing knowledge of the interacting Lagrangian. It w…
