暗物质研究与核物理

Dark Matter Studies Entrain Nuclear Physics

Susan Gardner, George Fuller

摘要:

我们回顾了理论上动机良好的暗物质候选人,和他们的发现途径,在最近的结果从对撞机物理学,天体物理学和宇宙学。总的来说,这些鼓励了对可能的暗物质候选者进行更广泛的思考-暗物质不一定是由“WIMP”组成的,即,具有弱尺度质量和相互作用的基本粒子。专门用于核物理的设施已经准备好研究某些非WIMP模型。与此同时,观测宇宙学的发展允许探测早期的相对论性能量密度,从而提供了新的方法来约束暗物质模型,前提是核物理学的输入是足够众所周知的。加速器,天体物理学和宇宙学的约束正在出现的汇合允许搜索暗物质候选者在更大的范围内的质量和相互作用强度比迄今为止可能的。

英文摘要:

We review theoretically well-motivated dark-matter candidates, and pathways to their discovery, in the light of recent results from collider physics, astrophysics, and cosmology. Taken in aggregate, these encourage broader thinking in regards to possible dark-matter candidates --- dark-matter need not be made of "WIMPs," i.e., elementary particles with weak-scale masses and interactions. Facilities dedicated to nuclear physics are well-poised to investigate certain non-WIMP models. In parallel to this, developments in observational cosmology permit probes of the relativistic energy density at early epochs and thus provide new ways to constrain dark-matter models, provided nuclear physics inputs are sufficiently well-known. The emerging confluence of accelerator, astrophysical, and cosmological constraints permit searches for dark-matter candidates in a greater range of masses and interaction strengths than heretofore possible.
