Soft-Theorems for Scalar Particles: The Dilatons Story (2203.07957v1)
Published 15 Mar 2022 in hep-th
Abstract: We summarize recent results regarding single and double soft theorems of two different particles named dilatons, the Nambu-Goldstone boson of the spontaneously broken conformal field theories and the massless scalar particle of the closed string theories. Similarities and differences between the soft theorems of these two particles are discussed as well as their connections with the symmetries of the theories.
