Scalar kink braneworlds and cosmology

Abstract

Our universe might be a domain wall or kink carrying localized standard model fields embedded in a 4 + 1-dimensional space. I report on some initial studies of the cosmology of such a model, focusing on the relatively simple de Sitter (dS) and Anti-de Sitter (AdS) cases for the effective 3 + 1-dimensional FRW metric. Fermion localization to the AdS4 and dS4 domain walls is briefly discussed. © World Scientific Publishing Company.
