对“暗物质的多散射恒星捕获“一文的评论
Comment on "Multiscatter stellar capture of dark matter"
摘要：
Bramante，Delgado和Martin [Phys. Rev. D96，063002（2017）.，BDM 17]以一种非常重要的方式扩展了暗物质（DM）捕获的分析形式，这在原则上允许使用紧凑的天体物理对象，如中子星（NS），作为暗物质探测器。在这篇评论中，我们指出存在的区域中的暗物质中子散射截面$(σ_{nX})$与暗物质质量$(m_{X})$，这种方法的约束力是失去了。这对应于NS必须具有的最高温度（$T_{crit}$），以便用作暗物质探测器。此外，我们指出了BDM17中的几个错别字和错误，这些错误并没有严重影响他们的结论。此外，我们提供了半解析近似的总捕获率的任意质量的暗物质粒子的各种限制制度。这些解析近似被用来验证我们的数值结果。
英文摘要：
Bramante, Delgado, and Martin [Phys. Rev. D96, 063002(2017)., hereafter BDM17] extended the analytical formalism of dark matter (DM) capture in a very important way, which allows, in principle, the use of compact astrophysical objects, such as neutron stars (NS), as dark matter detectors. In this comment, we point out the existence of a region in the dark matter neutron scattering cross section $(σ_{nX})$ vs. dark matter mass $(m_{X})$ where the constraining power of this method is lost. This corresponds to a maximal temperature ($T_{crit}$) the NS has to have, in order to serve as a dark matter detector. In addition, we point out several typos and errors in BDM17 that do not affect drastically their conclusions. Moreover, we provide semi-analytical approximations for the total capture rates of dark matter particle of arbitrary mass for various limiting regimes. Those analytical approximations are used to validate our numerical results.
