论文摘要
我们讨论了与标准模型（SM）的线性和二次耦合的超轻标量暗物质（DM）的模型。除了分别研究线性和二次相互作用的现象学外，我们还检查了它们的相互作用。我们回顾了可以探测这种相互作用并在参数空间上介绍当前和预期的未来界限的不同实验。特别是，我们讨论了[A. Hees，O。Minazzoli，E。Savalle，Y。V。Stadnik和P. Wolf，Phys.Rev.D 98（2018）6，064051]，并将其扩展到捕获DM场的线性和二次耦合的理论。此外，我们讨论了理论方面和对自然模型的相应挑战，其中二次相互作用具有现象学重要性。
We discuss models of ultralight scalar Dark Matter (DM) with linear and quadratic couplings to the Standard Model (SM). In addition to studying the phenomenology of linear and quadratic interactions separately, we examine their interplay. We review the different experiments that can probe such interactions and present the current and expected future bounds on the parameter space. In particular, we discuss the scalar field solution presented in [A. Hees, O. Minazzoli, E. Savalle, Y. V. Stadnik and P. Wolf, Phys.Rev.D 98 (2018) 6, 064051], and extend it to theories that capture both the linear and the quadratic couplings of the DM field to the SM. Furthermore, we discuss the theoretical aspects and the corresponding challenges for natural models in which the quadratic interactions are of phenomenological importance.
