论文摘要
新的轻量表玻色子会影响几个低能实验，例如原子奇偶校验或山脉。在这里，我们探讨了一个新的$ u（1）$量规对称性，而标准型号的门户是通过$ z-z'$质量混合的可能性。在我们的方法中，打破新规格对称性对于产生中微子质量至关重要。我们研究了重现中微子质量的参数空间，正确的暗物质遗物丰度，并在银河系中心产生观察到的类似核心的DM分布。
New light gauge bosons can affect several low-energy experiments, such as atomic parity violation or colliders. Here, we explore the possibility that a dark sector is charged under a new $U(1)$ gauge symmetry, and the portal to the Standard Model is through a $Z-Z'$ mass mixing. In our approach, breaking the new gauge symmetry is crucial to generate neutrino masses. We investigate the parameter space to reproduce neutrino masses, the correct dark matter relic abundance, and to produce the observed core-like DM distribution in galactic centers.
