Title: Soft particle theorems in effective field theory Abstract: In the limit where the energy and momentum of a particle goes to zero, its scattering processes behave in ways that reveal interesting and fundamental properties of the underlying particle interactions. This is encoded in "soft theorems" that have been studied in quantum field theory for many years. The subject has recently received renewed interested due to the discovery of its connection to so-called asymptotic symmetries. In this talk, I will review basic aspects of soft theorems in the modern context and describe novel modifications to the classic soft theorems that arise in the context of effective field theory.
