Asymptotic charges from soft scalars in even dimensions
Resumen:
We study asymptotic charges associated with a spin-zero analog of Weinberg's soft photon and graviton theorems in even dimensions. Simple spacetime expressions for the charges are given, but unlike gravity or electrodynamics, the symmetry interpretation for the charges remains elusive. This work is a higher dimensional extension of the four-dimensional case studied by Campiglia [Phys. Rev. D 97, 046002 (2018)]PRVDAQ2470-001010.1103/PhysRevD.97.046002.
