Vainshtein mechanism in Gauss-Bonnet gravity and Galileon aether

Vainshtein mechanism in Gauss-Bonnet gravity and Galileon aether

We derive field equations of Gauss-Bonnet gravity in 4 dimensions after dimensional reduction of the action and demonstrate that in this scenario Vainshtein mechanism operates in the flat spherically symmetric background. We show that inside this Vainshtein sphere the fifth force is negligibly small compared to the gravitational force. We …
