Title: 类矢量轻子作为暗物质冰山的尖端

Abstract: A vectorlike lepton could make up a tiny fraction of the dark matter. Its large Z-boson mediated direct detection cross section can compensate for the small relic abundance, giving rise to an interesting signal at future experiments---perhaps even the first one detected. We discuss how such a scenario might arise in the context of a simple non-thermal cosmology and investigate bounds from direct detection experiments and whether this scenario might be probed at the LHC. Searches for disappearing tracks appear promising. Show Chinese abstract

Abstract: 一种类似矢量的轻子可能构成暗物质的一小部分。 其较大的通过Z玻色子介导的直接探测截面可以弥补微弱的剩余丰度，从而在未来实验中产生有趣的信号——甚至可能是首次被探测到的信号。 我们讨论这种情形如何在简单的非热宇宙学背景下出现，并研究直接探测实验的限制，以及该情景是否可能在大型强子对撞机（LHC）上被检验。 对消失轨迹的搜索似乎很有希望。
