弛豫暗物质

Relaxion Dark Matter

Nayara Fonseca, Enrico Morgante

摘要:

我们强调了标准模型层次问题和暗物质部门之间的新联系。关键部分是弛豫场,它除了扫描希格斯质量和设定电弱尺度之外,还构成了观测到的宇宙暗物质丰度。松弛机制是在膨胀过程中实现的,必要的摩擦力是由粒子的产生提供的。使用这个框架,我们表明,弛豫是一个现象上可行的暗物质候选人在千电子伏的质量范围。

英文摘要:

We highlight a new connection between the Standard Model hierarchy problem and the dark matter sector. The key piece is the relaxion field, which besides scanning the Higgs mass and setting the electroweak scale, also constitutes the observed dark matter abundance of the universe. The relaxation mechanism is realized during inflation, and the necessary friction is provided by particle production. Using this framework we show that the relaxion is a phenomenologically viable dark matter candidate in the keV mass range.
