论文摘要

超轻的玻色子代表了一种有希望的暗物质候选者,表现出独特的波浪样行为。这些特性可以转移到深色介体,例如动力学混合光光子,这可能是暗模型和标准模型扇区之间的联系,从而导致其质量的周期性振荡。我们提出了一种使用对撞机和梁垃圾场实验中的暗介体检测到超轻暗物质的方法,将其与常规原子,分子和光学方法区分开来。深色介体质量的时间变化性质表现出双峰频谱,由于每个共振质量箱中的亮度暴露降低,传统的约束量减少了1至2个数量级。为了提高灵敏度,我们利用CMS打开数据中的事件时间戳记,并证明与时尚方法相比,该技术将灵敏度提高了大约一个数量级。此外,事实证明,它有效检测黑暗中介者的无形衰变。

The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors. These properties could transfer to the dark mediator, such as the kinetic mixing dark photon, which can be a link between the dark and Standard Model sectors, resulting in periodic oscillations of its mass. We propose a method to detect ultralight dark matter using dark mediators in collider and beam dump experiments, distinguishing it from conventional atomic, molecular, and optical methods. The time-varying nature of dark mediator mass exhibits a double-peak spectrum, reducing traditional constraints by 1 to 2 orders of magnitude, due to decreased luminosity exposure in each resonant mass bin. To enhance sensitivity, we utilize event time-stamps in the CMS Open Data and demonstrate that this technique boosts sensitivity by approximately one order of magnitude compared to the time-blind method. Moreover, it proves effective in detecting the invisible decay of the dark mediator.
