Smooth braneworld models possibility in modified gravities

Abstract

In this paper, it is shown that the consideration of the braneworld consistency conditions within the framework of bulk modified gravities allows for the existence of thick branes in the five-dimensional case with compact extra dimension. On studying the specific consistency conditions in the Brans-Dicke gravity, we were able to show that the brane generating scalar field potential is relevant for relaxing the gravitational constraints.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CBPF, BR-22290180 Rio De Janeiro, RJ, BrazilUniv Estadual Paulista, Dept Fis & Quim, Guaratingueta, SP, BrazilUniv Estadual Paulista, Dept Fis & Quim, Guaratingueta, SP, Brazi
