Title: μ子束作为宇宙中奇异滴的标志

Abstract: Recently the CERN ALICE experiment, in its dedicated cosmic ray run, observed muon bundles of very high multiplicities, thereby confirming similar findings from the LEP era at CERN (in the CosmoLEP project). So far their presence is still not fully understood. We propose as a possible explanation of this phenomenon that they could be produced by strangelets, hypothetical stable lumps of strange quark matter infiltrating our Universe. We also address the possibility of additionally deducing their directionality which could be of astrophysical interest. Significant evidence for anisotropy of arrival directions of these strangelets is found. Estimated directionality suggests their possible extragalactic provenance. Show Chinese abstract

Abstract: 最近，欧洲核子研究中心(ALICE)实验在专门的宇宙射线运行中，观察到了多粒子μ子束，从而证实了欧洲核子研究中心(在CosmoLEP项目中)在LEP时代的类似发现。 到目前为止，它们的存在仍未被完全理解。 我们提出，这种现象的一个可能解释是，它们可能是由奇异夸克物质的假设性稳定块——奇异滴——产生的，这些奇异滴渗透到我们的宇宙中。 我们还探讨了进一步推断它们方向性的可能性，这可能具有天体物理意义。 发现了这些奇异滴到达方向各向异性的显著证据。 估计的方向性表明它们可能起源于银河系外。
