通过对致密星的观测约束不对称暗物质

Constraining Asymmetric Dark Matter through observations of compact stars

Chris Kouvaris, Peter Tinyakov

摘要:

基于球状星团中白矮星和中子星的简单存在,我们对具有自旋相关相互作用的非对称暗物质候选者施加了限制。对于广泛的参数(WIMP质量和WIMP-核子截面),WIMP可以被大量捕获在原始恒星中,一旦原始恒星坍缩为白矮星或中子星,这些WIMP可能会自引力并最终坍缩形成最终摧毁恒星的迷你黑洞。我们施加竞争性的限制,直接暗物质搜索实验,质量下降到TeV规模的WIMP。

英文摘要:

We put constraints on asymmetric dark matter candidates with spin-dependent interactions based on the simple existence of white dwarfs and neutron stars in globular clusters. For a wide range of the parameters (WIMP mass and WIMP-nucleon cross section), WIMPs can be trapped in progenitors in large numbers and once the original star collapses to a white dwarf or a neutron star, these WIMPs might self-gravitate and eventually collapse forming a mini-black hole that eventually destroys the star. We impose constraints competitive to direct dark matter search experiments, for WIMPs with masses down to the TeV scale.
