A first-order approach to conformal gravity
Original language description
We investigate whether a spontaneously-broken gauge theory of the group SU(2, 2) may be a viable alternative to general relativity. The basic ingredients of the theory are an SU(2, 2) gauge field Aμ and a Higgs field W in the adjoint representation of the group with the Higgs field producing the symmetry breaking SU(2, 2) SO(1, 3) -> SO(1, 1). The action for gravity is polynomial in {Aμ,W} and the field equations are first-order in derivatives of these fields. The new SO(1, 1) symmetry in the gravitational sector is interpreted in terms of an emergent local scale symmetry and the existence of ‘conformalized’ general relativity and fourth-order Weyl conformal gravity as limits of the theory is demonstrated. Maximally symmetric spacetime solutions to the full theory are found and stability of the theory around these solutions is investigated.
