TDiff in the dark: gravity with a scalar field invariant under transverse diffeomorphisms
Abstract We reflect on the possibility of having a matter action that is invariant only under transverse diffeomorphisms. This possibility is particularly interesting for the dark sector, where no restrictions arise based on the weak equivalence principle. In order to implement this idea we consider...
