接触相互作用和亲顶标量暗物质

Contact interactions and top-philic scalar dark matter

Alan S. Cornell, Aldo Deandrea, Thomas Flacke, Benjamin Fuks, Lara Mason

摘要:

我们调查的现象学的标量top-philic暗物质候选人时,添加一个维度5接触相互作用项,作为动机的潜在扩展的标准模型,如复合希格斯模型。我们发现,接触相互作用的存在下,可以有一个重大的影响,暗物质遗迹密度以及其直接和间接的检测前景,而碰撞机现象的模型不受影响。这强调了对撞机和宇宙学约束对暗物质模型的互补性。

英文摘要:

We investigate the phenomenology of a scalar top-philic dark matter candidate when adding a dimension-five contact interaction term, as motivated by possible underlying extensions of the Standard Model such as composite Higgs models. We show that the presence of contact interactions can have a major impact on the dark matter relic density as well as on its direct and indirect detection prospects, while the collider phenomenology of the model is unaffected. This underlines the complementarity of collider and cosmological constraints on dark matter models.
