摘要
奇异滴,即质量较小的奇异夸克物质团块,有关它的研究涉及物理学的多个重要分支。如果存在奇异滴,人们对暗物质组分和致密星体结构的认识将会改变,强相互作用的研究也会有新的途径。已经有若干实验结果表明宇宙线中可能含有奇异滴成分。因此,研究宇宙线奇异滴的产生、传播及其与地球大气作用过程等是非常重要的。将重点围绕上述几个问题,综述目前奇异滴研究的现状。
Strangelets are lumps of strange quark matter, in the research of which many important branches of physics are involved. If strangelets exist in reality, our knowledge about dark matter and compact stars should be improved, and physicists have also an additional way to study the elementary color interaction. Strangelets could be one of the components of cosmic rays, especially of ultra-high energy cosmic rays. Therefore, it is very important to investigate the production, the propagation, and the observational features of interacting with the terrestrial atmosphere of strangelets as cosmic rays. The recent achievements of strangelets are reviewed, with attention being paid to the above issues.
