论文摘要
通货膨胀的全息时空模型(HST)模型对暗物质具有潜在的解释,例如微小的原始黑洞。在最近的Barrau \ cite {Barrau}的一篇论文中,我们提出了该模型的一个版本,其中一些通货膨胀的黑洞(IBHS)的衰减会导致热爆炸,带有最小的离散对称性费用价值。携带此费用的IBH的分数很难从第一原则中估算出来,但是我们要求在正确的温度$ t_ {eq} \ sim 1 ev = 10^{ - 28} m_p $下进行辐射和物质支配之间的交叉。分数很小,$ f \ sim 2 \ times 10^{ - 9} $,因此我们相信这给出了非常合理的暗物质模型。
The Holographic Space-time (HST) model of inflation has a potential explanation for dark matter as tiny primordial black holes. Motivated by a recent paper of Barrau\cite{barrau} we propose a version of this model where some of the Inflationary Black Holes (IBHs), whose decay gives rise to the Hot Big Bang, carry the smallest value of a discrete symmetry charge. The fraction $f$ of IBHs carrying this charge is difficult to estimate from first principles, but we fix it by requiring that the crossover between radiation and matter domination occurs at the correct temperature $T_{eq} \sim 1 eV = 10^{-28} M_P$. The fraction is small, $f \sim 2\times 10^{-9}$ so we believe this gives an extremely plausible model of dark matter.
