摘要
我们报告了 2010 年 5 月至 2012 年 5 月期间在 IceCube 中微子探测器内进行的全天域高能中微子事例搜寻结果。此次搜寻是对此前探测到两个 PeV 中微子事例的后续工作，具有更高的灵敏度，并将能量覆盖范围扩展至约 30 TeV。我们观测到了 26 个额外事例，数量 substantially 超过大气背景的预期。综合两次搜寻结果，在 水平上排除了这 28 个事例纯粹源于大气的可能性。这 28 个事例包括迄今观测到的能量最高的中微子，其味、方向和能量均与大气缪子和中微子背景的预期不符。然而，这些性质与关于地外起源额外成分的通用预测一致。

Revised version corrects the energy threshold for figure 7 (bottom) and one affiliation in the author list. The effective area (figure 7, top) is not affected and remains unchanged. The correction does not influence any of the results presented in the paper, and the text remains unchanged. Address correspondence to: Claudio Kopper, Naoko Kurahashi, Nathan Whitehorn
