标准模型U(1)扩展中的无菌中微子暗物质

Sterile neutrino dark matter in a U(1) extension of the standard model

Károly Seller

摘要:

我们探讨了在标准模型的U(1)扩展中产生暗物质的可能性,也称为超弱模型。冻结和冻结出的机制进行了详细描述,假设最轻的不育中微子模型中的暗物质的候选人。在这两种情况下,我们提出的超弱耦合与新的规范玻色子质量的平面上的青睐的参数空间。我们讨论了实验限制每种情况下,轮廓检测的可能性。

英文摘要:

We explore the possibilities of dark matter production in a U(1) extension of the standard model, also called the super-weak model. The freeze-in and freeze-out mechanisms are described in detail, assuming the lightest sterile neutrino in the model as the dark matter candidate. In both scenarios we present the favoured parameter space on the plane of super-weak coupling versus the new gauge boson mass. We discuss the experimental constraints limiting each case and outline possibilities of detection.
