Systematic construction of Low- energy effective theory Backgrounds characterized by ∂ φ and timelike μ ≠ 0 Background metric is maximally symmetric, either Minkowski or dS.
Gauge choice: φ( t , x) = t. Residual symmetry: x → x′ ( t, x) (Unitary gauge) Write down most general action invariant under this residual symmetry. ( Action for π: undo unitary gauge!) g = + Start with flat background μν μν δh = ∂ ξ + ∂ μν μ i Under residual ξ ν 0 h0i 0 i ν ξ μ ij μν η h δh = , δ = ∂ ξ , δh = ∂ ξ + ∂ ξ 00 π δφ ≡ = i j 0 j i
