宏观“夸克核”的电层：暗物质弥散MeV辐射源
The Electrosphere of Macroscopic "Quark Nuclei": A Source for Diffuse MeV Emissions from Dark Matter
摘要：
我们利用一个夸克-费米模型计算了夸克反物质块的电层结构，这些块被假定为构成了大部分的暗物质。这提供了一个单一的自洽的密度分布从超相对论密度的非相对论玻尔兹曼制度，用于目前微观合理的计算的几个属性的金块，包括他们的净电荷，和比例的MeV到511千电子伏的电子湮灭的排放量。我们发现，计算出的参数与以前的现象学估计的基础上的观测假设，金块是一个来源的几个原因不明的弥漫性排放的银河系。由于不需要任何唯象参数来描述这些观测，计算提供了另一个非平凡的验证暗物质的建议。电层的结构是相当普遍的，在奇夸克星的表面也是有效的，如果它们存在的话。
英文摘要：
Using a Thomas-Fermi model, we calculate the structure of the electrosphere of the quark antimatter nuggets postulated to comprise much of the dark matter. This provides a single self-consistent density profile from ultrarelativistic densities to the nonrelativistic Boltzmann regime that use to present microscopically justified calculations of several properties of the nuggets, including their net charge, and the ratio of MeV to 511 keV emissions from electron annihilation. We find that the calculated parameters agree with previous phenomenological estimates based on the observational supposition that the nuggets are a source of several unexplained diffuse emissions from the Galaxy. As no phenomenological parameters are required to describe these observations, the calculation provides another nontrivial verification of the dark-matter proposal. The structure of the electrosphere is quite general and will also be valid at the surface of strange-quark stars, should they exist.
