Phantom singularities in Kinetic Gravity Braiding theories

Scalar field theories known as Kinetic Gravity Braiding are renowned for the possibility of driving the expansion of the cosmos towards a future self-tuning de Sitter state when the corresponding Lagrangian is invariant under constant shifts in the scalar field. Nevertheless, this is not the only possible future phenomenology for these shift-symmetric models. In fact, I will argue that future cosmological singularities can also appear in this framework. As an example, I will present a simple model featuring a future big rip singularity.
