In 2004, Dharam Vir Ahluwalia and Daniel Grumiller discovered a dark matter candidate called Elko: spin one-half fermions with mass dimension one. These fermions are described by a spinorial Klein-Gordon formalism and very different from electrons or neutrinos. In this review, we give a brief introduction to the localization of Elko spinor fields on branes. First, we briefly review some brane-world theories and the localization of bulk matter fields on branes. Then, after a brief introduction to Elko spinor fields, we focus on the localization of Elko fields on branes in three cases: the free Elko fields, the Elko fields with Yukawa-like coupling, and finally, the Elko fields with non-minimal coupling.

2004年，达拉姆·维尔·阿卢瓦利亚（Dharam Vir Ahluwalia）和丹尼尔·格鲁米勒（Daniel Grumiller）发现了一种名为Elko的暗物质候选物：旋转质量尺寸为1的半费米子。这些费米子由脊髓型Klein-Gordon形式主义描述，与电子或中微子非常不同。在这篇综述中，我们简要介绍了Elko棘突场在麸皮上的定位。首先，我们简要回顾一下一些麸皮世界的理论以及麸皮上的大块物质场的定位。然后，在简要介绍了Elko旋子场之后，我们将重点介绍三种情况下的Elko场在麸皮上的定位：自由Elko场，具有Yukawa型耦合的Elko场以及最后具有非最小耦合的Elko场。
