Electron anti-neutrinos at the Glashow resonance (GR, at PeV) have an enhanced probability to be detected. With three neutrinos detected by IceCube in the (1–2) PeV energy range at present, one would expect that about 1 to 4 GR should have been detected. The high-energy ∼8.7 PeV muon neutrino detected by IceCube may not be a GR event. If so, we expect to detect 50 to 70 GR , then one would have a “missing Glashow-resonance problem”. This would suggest (1) that pγ interaction rather than pp interaction is the dominant channel to produce the observed IceCube high-energy neutrinos; (2) that multi-pion pγ interactions are suppressed; and (3) that the magnetic field and photon energy density in the pγ emission region is such that significant cooling occurs before decaying, yet 's essentially do not cool before decaying.

关于在IceCube中未检测到Glashow共振
电子反中微子在Glashow共振(GR,at PeV)的概率更高。目前,IceCube在(1-2)PeV能量范围内检测到3个中微子,人们可以预期大约有1至4 GR应该已经被检测到。IceCube检测到的高能量〜8.7 PeV的μ子中微子可能不是GR事件。如果是这样,我们预计将检测到50到70 GR,那么就会有一个“缺少Glashow共振问题”。这表明(1)pγ相互作用而不是pp相互作用是产生观察到的IceCube高能中微子的主要渠道;(2)抑制了多pionpγ相互作用;(3)pγ发射区域的磁场和光子能量密度非常大 冷却发生在腐烂之前 在腐烂之前基本上不冷却。
