标题： Nuclear Production and Analytic Attenuation of Energetic MeV Solar Dark Matter

摘要： 我们提出一种MeV暗物质的太阳能生成机制，以克服直接探测实验中的能量阈值。 特别是，质子和氘核融合到${}^3 \mathrm{He}$的$pp$链，产生具有5.5$\,$MeV能量释放的高能中微子和伽马光子，也可以产生一对暗物质粒子。 此外，我们建立了一个使用玻尔兹曼方程研究太阳对产生的暗物质通量的衰减效应的分析公式。 投影灵敏度以DarkSide-LowMass实验中的氩靶为例进行说明。 显示英文摘要

摘要： We propose a solar production mechanism of MeV dark matter to overcome the energy threshold in direct detection experiments. In particular, the proton and deuteron fussion to ${}^3 \mathrm{He}$ of the $pp$ chain that produces energetic neutrino and gamma photon with 5.5$\,$MeV of energy release can also produce a pair of dark matter particles. Besides, we establish an analytical formalism of using the Boltzmann equation to study the solar attenuation effect on the produced dark matter flux. The projected sensitivity is illustrated with Argon target at the DarkSide-LowMass experiment.
