Local transformations of units in Scalar-Tensor Cosmology
Riccardo Catena, Massimo Pietroni, Luca Scarabello
Abstract
The physical equivalence of Einstein and Jordan frame in Scalar Tensor theories has been explained by Dicke in 1962: they are related by a local transformation of units. We discuss this point in a cosmological framework. Our main result is the construction of a formalism in which all the physical observables are frame-invariant. The application of this approach to CMB codes is at present under analysis.
