Atomki异常和隐蔽的黑暗部门

Atomki anomaly and the Secluded Dark Sector

Yasuhiro Yamamoto

摘要:

Atomiki异常可以解释为一种新的光矢量玻色子。如果这样的新粒子存在,它可能是标准模型扇区和包括暗物质在内的暗扇区之间的媒介。我们讨论了一些简单有效的模型与这些粒子。在这些模型中,隐蔽的暗物质模型是很好的候选者,以满足热遗迹丰度。特别是,我们发现,如果暗物质是费米子,那么暗物质的自相互作用可以大到足以解决小尺度结构之谜。

英文摘要:

The Atomiki anomaly can be interpreted as a new light vector boson. If such a new particle exists, it could be a mediator between the Standard Model sector and the dark sector including the dark matter. We discussed some simple effective models with these particles. In the models, the secluded dark matter models are good candidates to satisfy the thermal relic abundance. In particular, we found that the dark matter self-interaction can be large enough to solve the small scale structure puzzles if the dark matter is a fermion.
