论文摘要
暗物质尺度上暗物质（DM）的短距离行为表现出了几个特征，该特征未由典型的冷暗物质（CDM）与速度无关的横截面所解释。我们讨论了一个粒子物理模型，隐藏的扇区与可见的扇形易于相互作用，在该扇区中，黑暗的羊式自我互动通过黑色的黑力以浅色黑色光子作为介体。我们研究了涉及两个温度的耦合玻尔兹曼方程，一个用于每个部门。我们将依赖速度的DM横截面与矮星系尺度的数据拟合到与遗物密度约束一致的簇。
The short distance behavior of dark matter (DM) at galaxy scales exhibits several features not explained by the typical cold dark matter (CDM) with velocity-independent cross-section. We discuss a particle physics model with a hidden sector interacting feebly with the visible sector where a dark fermion self-interacts via a dark force with a light dark photon as the mediator. We study coupled Boltzmann equations involving two temperatures, one for each sector. We fit the velocity-dependent DM cross-section to the data from scales of dwarf galaxies to clusters consistent with relic density constraint.
