Disforming to Conformal Symmetry
arXiv:2207.12611 · doi:10.1088/1475-7516/2022/11/019
Abstract
We analyse the dynamical properties of disformally transformed theories of gravity. We show that disformal transformation typically introduces novel degrees of freedom, equivalent to the mimetic dark matter, which possesses a Weyl-invariant formulation. We demonstrate that this phenomenon occurs in a wider variety of disformal transformations than previously thought.
