Ghosts, Strong Coupling and Accidental Symmetries in Massive Gravity
Cedric Deffayet, Jan-Willem Rombouts
We show that the strong self-interaction of the scalar polarization of a massive graviton can be understood in terms of the propagation of an extra ghost-like degree of freedom, th…
Naturalness in Cosmological Initial Conditions
F. Nitti, M. Porrati, J. -W. Rombouts
We propose a novel approach to the problem of constraining cosmological initial conditions. Within the framework of effective field theory, we classify initial conditions in terms…
Metastable gravity on classical defects
Christophe Ringeval, Jan-Willem Rombouts
We discuss the realization of metastable gravity on classical defects in infinite-volume extra dimensions. In dilatonic Einstein gravity, it is found that the existence of metastab…
Strong Coupling vs. 4-D Locality in Induced Gravity
M. Porrati, J. -W. Rombouts
We re-examine the problem of strong coupling in a regularized version of DGP (or ``brane-induced'') gravity. We find that the regularization of ref. hep-th/0304148 differs from DGP…
Regularization of Brane Induced Gravity
Marko Kolanovic, Massimo Porrati, Jan-Willem Rombouts
We study the regularization of theories of ``brane induced'' gravity in codimension . The brane can be interpreted as a thin dielectric with a large dielectric constant, embed…
