A no-hair theorem for the galileon    [PDF]

Lam Hui, Alberto Nicolis

We consider a galileon field coupled to gravity. The standard no-hair
theorems do not apply, because of the galileon's peculiar derivative
interactions. We prove that, nonetheless, static spherically symmetric black
holes cannot sustain non-trivial galileon profiles. Our theorem holds
regardless of whether there are non-minimal couplings between the galileon and
gravity of the covariant galileon type.
