复合暗物质与暗物质之谜
Composite Dark Matter and Puzzles of Dark Matter Searches
摘要:
DAMA/NaI和DAMA/LIBRA实验中暗物质搜索的积极结果,与其他小组的结果放在一起,可能意味着宇宙学暗物质的非平凡粒子物理解决方案。带-2电荷的稳定粒子,在O-氦“原子”(OHe)中与原始氦结合,代表了暗物质的一种特定的比冷的核相互作用形式。在地球物质中OHe的速度变慢,因此在低温实验中直接探测地下暗物质的方法是难以实现的。然而,在DAMA/NaI和DAMA/LIBRA实验中,Na和I核对OHe的辐射俘获会导致能量释放在2-5 keV区间内的年变化。
英文摘要:
Positive results of dark matter searches in DAMA/NaI and DAMA/LIBRA experiments, being put together with the results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter. Stable particles with charge -2, bound with primordial helium in O-helium "atoms" (OHe), represent a specific Warmer than Cold nuclear-interacting form of dark matter. Slowed down in the terrestrial matter, OHe is elusive for direct methods of underground Dark matter detection used in cryogenic experiments. However radiative capture of OHe by Na and I nuclei can lead to annual variations of energy release in the interval of energy 2-5 keV in DAMA/NaI and DAMA/LIBRA experiments.
