论文摘要
这项工作的目的是找到意外复合暗物质模型的最简单的紫外线完成，该模型可以动态地生成对暗物质候选者的不对称性，最轻的深色巴里昂，并同时消灭了对称成分。在此框架中，暗物质是一个限制的$ \ mathrm {su}（n）$ gauge组的意外稳定界限状态，该状态可能与可见扇区弱相互作用。这种候选者的不对称产生是通过质量标量$ ϕ $的两种口味的不平衡衰减发生的，其中质量$ m_ϕ> 10^{10} $ gev。低于这样的规模，模型恢复了候选暗物质的意外稳定性或长寿。如果深色重子的质量<75 tev，则将对称成分消灭了残留的限制相互作用。
The goal of this work is to find the simplest UV completions of Accidental Composite Dark Matter models that can dynamically generate an asymmetry for the Dark Matter candidate, the lightest dark baryon, and simultaneously annihilate the symmetric component. In this framework Dark Matter is an accidentally stable bound state of a confining $\mathrm{SU}(N)$ gauge group that can interact weakly with the visible sector. The generation of asymmetry for such candidate happens via the out-of-equilibrium decay of two flavors of a heavy scalar $ϕ$, with mass $M_ϕ> 10^{10}$ GeV. Below such scale, the models recover accidental stability, or long-livedness, of the Dark Matter candidate. The symmetric component is annihilated by residual confined interactions provided that the mass of the dark baryon is < 75 TeV.
