论文摘要
尽管研究了数十年，但宇宙中“暗物质”的物理起源仍然难以捉摸。在这封信中，我们计算了一个全新的暗物质候选者的特性-Bose-Einstein冷凝物是由$ \ Mathbf {d^*（2380）} $ hexaquark形成的最近发现的骨气粒子。在第一项研究中，我们显示了稳定的$ \ Mathbf {d^*（2380）} $ Bose-Einstein冷凝物在原始的早期宇宙中可能形成，生产率足够大，以至于它们是黑物质的合理新候选者。还提出了这种暗物质的一些可能的天文签名。
Despite many decades of study the physical origin of "dark matter" in the Universe remains elusive. In this letter we calculate the properties of a completely new dark matter candidate - Bose-Einstein condensates formed from a recently discovered bosonic particle in the light-quark sector, the $\mathbf{ d^*(2380)}$ hexaquark. In this first study, we show stable $\mathbf{ d^*(2380)}$ Bose-Einstein condensates could form in the primordial early universe, with a production rate sufficiently large that they are a plausible new candidate for dark matter. Some possible astronomical signatures of such dark matter are also presented.
