介子束作为宇宙奇异性的标志
Muon bundles as a sign of strangelets from the Universe
摘要：
最近，欧洲核子研究中心的ALICE实验，在其专门的宇宙射线运行中，观察到非常高多重性的μ子束，从而证实了欧洲核子研究中心LEP时代（在CosmoLEP项目中）的类似发现。最初有人认为，它们显然来自质量很大的初级宇宙射线。我们提出了另一种可能性，认为最高多重性的μ子束是由奇异的，假设稳定的奇异夸克物质块渗透我们的宇宙。我们还讨论了额外推断它们的方向性的可能性，这可能是天体物理学的兴趣。发现了观测到的高多重数μ子束到达方向各向异性的重要证据，估计方向性表明它们可能来自河外。
英文摘要：
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). Originally it was argued that they apparently stem from the primary cosmic rays with a heavy masses. We propose an alternative possibility arguing that muonic bundles of highest multiplicity are 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 the observed high multiplicity muonic bundles is found. Estimated directionality suggests their possible extragalactic provenance.
