Query: "Conserved charges" of the Bondi-Metzner-Sachs algebra in the
  Brans-Dicke theory   The asymptotic symmetries in Brans-Dicke theory are analyzed using Penrose's
conformal completion method, which is independent of the coordinate system
used. These symmetries indeed include supertranslations and Lorentz
transformations for an asymptotically flat spacetime. With the Wald-Zoupas
formalism, "conserved charges" and fluxes of the Bondi-Metzner-Sachs algebra
are computed. The scalar degree of freedom contributes only to the Lorentz
boost charge, although it plays a role in various fluxes. The flux-balance laws
are further used to constrain displacement memory, spin memory and
center-of-mass memory effects.
