Beyond Fab Four
arXiv:1507.05942 · doi:10.1088/0264-9381/32/24/242001
Abstract
We show that the two additional Lagrangians that appear in theories beyond Horndeski can be reexpressed in terms of simple generalizations of the "John" and "Paul" terms of the Fab Four theories. We find that these extended Fab Four satisfy the same properties of self-tuning as the original Fab Four.
