Scalar-Vector Effective Field Theories from Soft Limits

Abstract

We give an overview of the implementation of the soft-bootstrap method applied to the landscape of theories where the Special Galileon couples to a massless vector particle. We also describe the corresponding traditional Lagrangian approach for this model, which takes into account the formal geometrical interpretation of the Special Galileon as fluctuations of a $D$-dimensional brane embedded in a $2D$-dimensional flat space.
