Linearized physics and gravitational-waves polarizations in the Palatini formalism of GBD theory
A generalized Brans-Dicke (GBD) theory in the framework of Palatini formalism is proposed in this paper. We derive the field equations by using the variational approach and obtain the linearized equations by using the weak-field approximation method. We show various properties of the geometrical sca...
