论文摘要
我们探讨了以下建议：中子终身难题可以通过过程中的中子腐烂到暗物质，n \ rightarrowχχχCχχChave，χhavave的质量是中子的三分之一。特别是，我们检查了这种衰减模式对中子恒星特性的后果。与早期建议的衰减模式不同，为了满足中子恒星质量和潮汐变形的约束，无需在暗物质颗粒之间具有强烈的排斥力。这项研究表明，有可能在中子恒星的核心上有热物质，并提出了暗物质冷却的可能机制，并检查中子出生后的中子恒星内中性子衰减的可能信号。
We explore the suggestion that the neutron lifetime puzzle might be resolved by neutrons decaying into dark matter through the process, n \rightarrow χχχ, with χhaving a mass one third of that of the neutron. In particular, we examine the consequences of such a decay mode for the properties of neutron stars. Unlike an earlier suggested decay mode, in order to satisfy the constraints on neutron star mass and tidal deformability, there is no need for a strong repulsive force between the dark matter particles. This study suggests the possibility of having hot dark matter at the core of the neutron star and presents a possible mechanism of dark matter cooling, and examines the possible signal of neutrons decaying in this way inside the neutron star right after its birth.
