Smooth braneworld in 6-dimensional asymptotically AdS spacetime

Abstract In this paper, we investigate a six-dimensional smooth thick braneworld model which contains a compact extra dimension and an infinite large one. The braneworld is generated by a real scalar field with a ϕ 6 potential and the bulk is an asymptotically AdS6 spacetime. The geometry achieves the localization of the free U(1) gauge field, which is a problem in five-dimensional Randall-Sundrum-like models. In addition, we analyze the stability of the braneworld system and the localization of the graviton.
