Spherically symmetric solutions of massive gravity and the Goldstone picture

Spherically symmetric solutions of massive gravity and the Goldstone picture

I will discuss spherically symmetric solutions of massive gravity. In particular, I will concentrate on the decoupling limit, for which the Goldstone picture is especially useful. I consider the Vainshtein mechanism in the decoupling limit and show that apart from the Vainshtein scaling, another scaling is also possible which leads to the restoring of General Relativity in the non-linear regime. Depending on the choice of the potential there can be either a regular solution with different asymptotic behaviors, or a singular solution. I will also discuss possible issues for the full system.
