论文摘要
\ cite {zhitnitsky} - \ cite {zhitnitsky13}中引入的斧头夸克掘金是冷暗物质的候选者，此外，这些候选者可能与男性生成相关。目前的工作研究了他们的演变，直到进入颜色超导阶段。在\ cite {zhitnitsky5}中已经考虑了这种进化，得出的结论是，大部分物体都诱导了大型化学势$μ$。在\ cite {zhitnitsky5}中，在物体周围的域壁上积累的重子数，并建议补偿内部和外部通量，可以忽略并可以忽略。在目前的工作中，对重子数字的大量贡献可能在初始阶段相关，并且该对象可能会考虑大量由于夸克 - 易夸克（Quark-antiquark）歼灭而引起的大量中微子。结果是对物体的更暴力收缩，也许是更有效的冷却。因此，结果对象的尺寸可能较小。即使考虑到这些更正，也得出结论，这些物体的宇宙学应用不会被宠坏。这些应用程序沿着文本讨论。
The axion quark nuggets introduced in \cite{zhitnitsky}-\cite{zhitnitsky13} are a candidate for cold dark matter which, in addition, may be relevant in baryogenesis scenarios. The present work studies their evolution till they enter in the colour superconducting phase. This evolution was already considered in \cite{zhitnitsky5}, where it is concluded that a large chemical potential $μ$ is induced on the bulk of the object. The baryon number accumulated at the domain wall surrounding the object is taken as predominant in \cite{zhitnitsky5}, and it is suggested that internal and external fluxes are compensated and can be neglected. In the present work, the possibility that the bulk contribution to the baryon number may be relevant at initial stages and that the object may emit a large amount of neutrinos due to quark-antiquark annihilations is taken into account. The outcome is a more violent contraction of the object and, perhaps, a more effective cooling. Therefore, the resulting objects may have a smaller size. Even taking into account these corrections, it is concluded that the cosmological applications of these objects are not spoiled. These applications are discussed along the text.
