论文摘要
暗物质直接检测实验旨在寻找用病毒速度移动的暗物质颗粒的散射$ \ sim 10^{ - 3} $。在这些速度下，检测器中的能量沉积足够大，可以引起电离/闪烁，形成了一类特征，在此类实验中寻找。这些实验对大型暗物质模型视而不见，这些模型与标准模型具有相对较大的散射横截面，导致暗物质与大气和岩石覆盖层经历了多个散射，因此在到达地下探测器之前会大大减慢。我们建议通过寻找对屏蔽且敏感的量热计的异常加热来搜索这类暗物质。在此探测器概念中，暗物质被岩石覆盖量进行了热能，但能够穿过探测器的热罩，从而导致异常加热。使用正在开发的Edelweiss和SuperCDMS的技术，我们估计了这种量热探测器的灵敏度。除了具有较大暗物质的模型 - 标准模型相互作用外，这些探测器还具有探测深色光子暗物质的能力。
Dark matter direct detection experiments are designed to look for the scattering of dark matter particles that are assumed to move with virial velocities $\sim 10^{-3}$. At these velocities, the energy deposition in the detector is large enough to cause ionization/scintillation, forming the primary class of signatures looked for in such experiments. These experiments are blind to a large class of dark matter models where the dark matter has relatively large scattering cross-sections with the standard model, resulting in the dark matter undergoing multiple scattering with the atmosphere and the rock overburden, and thus slowing down considerably before arriving at underground detectors. We propose to search for these kinds of dark matter by looking for the anomalous heating of a well shielded and sensitive calorimeter. In this detector concept, the dark matter is thermalized with the rock overburden but is able to pierce through the thermal shields of the detector causing anomalous heating. Using the technologies under development for EDELWEISS and SuperCDMS, we estimate the sensitivity of such a calorimetric detector. In addition to models with large dark matter - standard model interactions, these detectors also have the ability to probe dark photon dark matter.
