振荡自旋2暗物质

Oscillating Spin-2 Dark Matter

Luca Marzola, Martti Raidal, Federico R. Urban

摘要:

我们表明,从双度规理论自旋2场的相干振荡可以很容易地解释所观察到的暗物质丰度。我们得到了宇宙学背景下的场的运动方程,并详细讨论了模型的唯象性。该框架可以在原子钟中振荡电荷的精确测量中进行测试,使用原子光谱学和专用共振质量检测器以及类轴子粒子实验,因此为探测和测试引力本身提供了一个新的窗口。我们还评论了直接实现重力发条机制的框架的可能的多度量扩展。

英文摘要:

We show that the coherent oscillations of a spin-2 field from bimetric theory can easily account for the observed dark matter abundance. We obtain the equation of motion for the field in a cosmological setting and discuss in detail the phenomenology of the model. The framework is testable in precision measurements of oscillating electric charge in atomic clocks, using atomic spectroscopy and in dedicated resonant mass detectors as well as in axion-like-particles experiments, which therefore provide a new window to probe and test gravity itself. We also comment on possible multimetric extensions of the framework that straightforwardly implement the clockwork mechanism for gravity.
