尽管经过几十年的研究,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-玻色-爱因斯坦凝聚体的性质,该凝聚体是由最近在轻夸克扇区中发现的玻色粒子d*(2380)六夸克形成的。在第一项研究中,我们表明稳定的d*(2380)玻色-爱因斯坦凝聚体可以在原始的早期宇宙中形成,其产生速率足够大,它们是暗物质的一个合理的新候选者。一些可能的天文签名,这样的暗物质也提出。
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 d*(2380) hexaquark. In this first study, we show stable 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.
