论文摘要
利用电子激发的直接检测实验正在率先寻找光，子GEV，暗物质（DM）。因此，对于此制度中的任何DM电子相互作用率，具有准确的预测至关重要。超过DM（用于直接检测暗物质的电子激发的扩展计算）计算DM电子相互作用速率，并通过各种从头算电子结构计算的输入进行输入。本手稿的目的是两个方面：使用户熟悉超过DM的形式主义和输入，并执行新颖的计算以展示超过DM的能力。我们执行四个计算，这些计算扩展了先前的结果：深色光子模型中的散射速率，使用数值计算的介电函数筛选，散射速率具有相互作用势取决于电子速度，标量，伪镜和矢量DM的扩展吸收计算，以及散射速率的年度调节速度。
Direct detection experiments utilizing electronic excitations are spearheading the search for light, sub-GeV, dark matter (DM). It is thus crucial to have accurate predictions for any DM-electron interaction rate in this regime. EXCEED-DM (EXtended Calculation of Electronic Excitations for Direct detection of Dark Matter) computes DM-electron interaction rates with inputs from a variety of ab initio electronic structure calculations. The purpose of this manuscript is two-fold: to familiarize the user with the formalism and inputs of EXCEED-DM, and perform novel calculations to showcase what EXCEED-DM is capable of. We perform four calculations which extend previous results: the scattering rate in the dark photon model, screened with the numerically computed dielectric function, the scattering rate with an interaction potential dependent on the electron velocity, an extended absorption calculation for scalar, pseudoscalar, and vector DM, and the annual modulation of the scattering rate in the dark photon model.
