Degenerate Higher Order Scalar Tensor theories beyond Horndeski

Synopsis

This seminar will present scalar tensor theories whose Lagrangian contains second order derivatives of a scalar field and which propagate only one scalar mode, in addition to the two tensor modes. These theories encompass and extend the so-called Horndeski theories. I will discuss some phenomenological aspects of these new theories.
