Understand
We consider the recently introduced "galileon" field in a dynamical spacetime.
- When the galileon is assumed to be minimally coupled to the metric, we underline that both field equations of the galileon and the metric involve up to third-order derivatives.
- We show that a unique nonminimal coupling of the galileon to curvature eliminates all higher derivatives in all field equations, hence yielding second-order equations, without any extra propagating degree of freedom.
- The resulting theory breaks the generalized "Galilean" invariance of the original model.
