Braneworld solutions from scalar field in bimetric theory    [PDF]

D. Bazeia, F. A. Brito, F. G. Costa

We investigate the presence of braneworld solutions in a bimetric theory, with gravity and the scalar field coupling differently. We consider a non-standard model, with a Cuscuton-like scalar field, and we show how to generate braneworld solutions in this new scenario. In particular, we found no gravitational instabilities for the braneworld solutions.
