Running soft theorems in effective field theory
Jonah Berean-Dutcher, Maria Derda, Riley Stewart
We study soft theorems for photons and pions with local effective field theory (EFT) corrections up to one loop order. In massive QED with a dimension-five Pauli operator, the loca…

Soft Theorems from Higher Symmetries
Jonah Berean-Dutcher, Maria Derda, Julio Parra-Martinez
We describe the connection between spontaneously-broken higher symmetries and soft theorems for scattering amplitudes of their associated Nambu-Goldstone bosons. Our main result is…
