We investigate the presence of braneworld solutions in a bimetric theory, with gravity and the scalar field coupling differently. We consider a nonstandard 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. DOI: 10.1103/PhysRevD.87.065007
