摘要:
在夸克块模型中,暗物质粒子可由大量夸克或反夸克组成的致密复合天体表示。由于与可见物质的强相互作用,反夸克块应以地球上罕见的大气事件形式显现。它们可能在地球大气层中产生类似于流星轨迹的电离尾迹。然而,存在若干特征使人们能够区分反夸克块轨迹与流星轨迹。我们研究了反夸克块在空气中产生电离尾迹的特性,并表明它们可被标准流星雷达探测器记录。未观测到此类轨迹将夸克块模型中的平均重子荷数推高,要求 $|B|>4\ imes 10^{27}$。
英文摘要:
Within the quark nugget model, dark matter particles may be represented by compact composite objects composed of a large number of quarks or antiquarks. Due to strong interaction with visible matter, antiquark nuggets should manifest themselves in the form of rare atmospheric events on the Earth. They may produce ionized trails in the atmosphere similar to the meteor trails. There are, however, several features which should allow one to distinguish antiquark nugget trails from meteor ones. We study the properties of ionized trails from antiquark nuggets in the air and show that they may be registered by standard meteor radar detectors. Non-observation of such trails pushes up the mean baryon charge number in the quark nugget model, $|B|>4\times 10^{27}$.
