论文摘要
除了它不与标准模型或自身相互作用的事实之外,对暗物质知之甚少,否则确实如此弱。鉴于无需定理反对其相互作用的历史,自然候选人是更高的自旋场。在这里,我们开发了更高旋转(自旋$ s> 2 $)暗物质的情况。我们表明,在通货膨胀期间,超重量的玻色剂较高自旋场的重力产生可以提供我们今天观察到的所有暗物质。我们考虑可观察到的特征,并在方向直接检测中找到玻色粒高旋质暗物质的潜在特征。我们发现,对双重差分坐后速率有明显的自旋依赖性贡献,这补充了宇宙微波背景中较高自旋场的振荡烙印。我们考虑扩展到更高的自旋费米子和超对称性的上旋转。
Little is known about dark matter beyond the fact that it does not interact with the standard model or itself, or else does so incredibly weakly. A natural candidate, given the history of no-go theorems against their interactions, are higher spin fields. Here we develop the scenario of higher spin (spin $s>2$) dark matter. We show that the gravitational production of superheavy bosonic higher spin fields during inflation can provide all the dark matter we observe today. We consider the observable signatures, and find a potential characteristic signature of bosonic higher spin dark matter in directional direct detection; we find that there are distinct spin-dependent contributions to the double differential recoil rate, which complement the oscillatory imprint of higher spin fields in the cosmic microwave background. We consider the extension to higher spin fermions and supersymmetric higher spins.
