论文摘要
我们探索了一类简化的扩展，该扩展包含一个复杂的单重标量标量作为暗物质候选者，并伴随着矢量样的Lepton作为介体，都在新的$ Z_3 $对称性下收取。以最简单的形式，新的物理伴侣仅与右撇子电子伴侣，并且该模型能够容纳围绕电动左右的正确的暗物质遗物丰度，直至几个TEV，从扰动，对撞击器和深色物质搜索中避免了最强的约束。此外，该模型能够通过几个数量级来增强天然正电子通量，并显示盒形光谱。该框架取决于新领域的量子电荷分配，从而打开了许多现象学的可能性。
We explore a class of simplified extensions to the Standard Model containing a complex singlet scalar as a dark matter candidate accompanied by a vector-like lepton as a mediator, both charged under a new $Z_3$ symmetry. In its simplest form, the new physics couples only to right-handed electrons, and the model is able to accommodate the correct dark matter relic abundance around the electroweak scale up to several TeV evading the strongest constraints from perturbativity, collider and dark matter searches. Furthermore, the model is capable to enhance naturally positron fluxes by several orders of magnitude presenting a box-shape spectra. This framework opens up a lot of phenomenological possibilities depending on the quantum charge assignments of the new fields.
