论文摘要
我们介绍了针对轻丝$^4 $ He的新签名检测新签名的分析：三个声子的发射。我们表明，在MEV下方的质量区域中，此过程的运动学可以提供一种重建暗物质相互作用顶点的方法，同时通过巧合要求和方向性提供背景拒绝。我们开发了所有必要的技术来处理这种可观察的技术，并计算相关的差分分布。
We present the analysis of a new signature for light dark matter detection with superfluid $^4$He: the emission of three phonons. We show that, in a region of mass below the MeV, the kinematics of this process can offer a way to reconstruct the dark matter interaction vertex, while providing background rejection via coincidence requirements and directionality. We develop all the necessary technology to deal with such an observable, and compute the associated differential distributions.
