Effective theory for the Vainshtein mechanism from the Horndeski action
PHYSICAL REVIEW D, no. 2 (2013)
摘要
Starting from the general Horndeski action, we derive the most general effective theory for scalar perturbations around flat space that allows us to screen fifth forces via the Vainshtein mechanism. The effective theory is described by a generalization of the Galileon Lagrangian, which we use to study the stability of spherically symmetri...更多
