Double-soft behavior of the dilaton of spontaneously broken conformal invariance
Abstract The Ward identities involving the currents associated to the spontaneously broken scale and special conformal transformations are derived and used to determine, through linear order in the two soft-dilaton momenta, the double-soft behavior of scattering amplitudes involving two soft dilaton...
