摘　　要：Owing to the special structure of a five-dimensional Elko spinor,its localization on a brane with codimension one becomes completely different from that of a Dirac spinor.By introducing the coupling between the Elko spinor and the scalar field that can generate the brane,we have two types of localization mechanism for the five-dimensional Elko spinor zero mode on a brane.One is the Yukawa-type coupling,and the other is the non-minimal coupling.In this study,we investigate the localization of the Elko zero mode on de Sitter and Anti-de Sitter thick branes with the two localization mechanisms,respectively.The results show that both the mechanisms can achieve localization.The forms of the scalar coupling function in both localization mechanisms have similar properties,and they play a similar role in localization.
