没有头?没有天文学!

No Tau? No Astronomy!

Daniele Fargion, Pietro Oliva

摘要:

自2013年以来,IceCube级联阵雨突然过剩已经显示出超过30-60 TeV到PeV能量的快速味道变化。这种从TeV的主要μ子轨道到更高能量的簇射事件的变化,归功于中微子天文学的新注入。然而,最近公布的54个中微子HESE,高能起始事件,以及38个由冰立方周围形成的槽形μ子产生的外部μ子径迹,没有一个指向任何预期的X-γ或射电源:没有一个与GRB有关,没有指向活动BL Lac,也没有指向费米目录中的AGN源。与附近的质量分布(本星系群)没有明显的相关性,也与银道面没有明显的相关性。此外,还没有任何记录(在十几个200 TeV的能量事件中)由于τ中微子的诞生和衰变而引起的预期的双爆炸。一个令人惊讶和令人惊讶的不公平分配的味道与预期的民主之一。最后,内HESE事件谱和外交叉μ子径迹谱并不完全一致。此外,在60 TeV处明显的天体物理学中微子通量突然增加,可能也会在几PeV处突然被切断,以隐藏(尚未观测到的)6.3 PeV处的希霍共振峰。一种更为快速的迷人的大气中微子成分可以解释冰立方的大部分谜团。如果在不久的将来,2017-2018年,它不会在某个地方发出τ中微子信号(通过AUGER,TA,ASHRA或IceCube中的双爆炸中的τ空气簇射),那么将面临一系列后果。这些缺失的相关性,特别是tau信号的缺失迫使我们声称:没有Tau?没有中微子天文学。

英文摘要:

Since 2013 IceCube cascade showers sudden overabundance have shown a fast flavor change above 30-60 TeV up to PeV energy. This flavor change from dominant muon tracks at TeVs to shower events at higher energies, has been indebted to a new injection of a neutrino astronomy. However the recent published 54 neutrino HESE, high energy starting events, as well as the 38 external muon tracks made by trough going muon formed around the IceCube, none of them are pointing to any expected X-gamma or radio sources: no one in connection to GRB, no toward active BL Lac, neither to AGN source in Fermi catalog. No clear correlation with nearby mass distribution (Local Group), nor to galactic plane. Moreover there have not been any record (among a dozen of 200 TeV energetic events) of the expected double bang due to the tau neutrino birth and decay. An amazing and surprising unfair distribution in flavor versus expected democratic one. Finally there is not a complete consistence of the internal HESE event spectra and the external crossing muon track ones. Moreover the apparent sudden astrophysical neutrino flux rise at 60 TeV might be probably also suddenly cut at a few PeV in order to hide the (unobserved , yet) Glashow resonance peak at 6.3 PeV. A more mondane prompt charmed atmospheric neutrino component may explain most of the IceCube puzzles. If this near future, 2017-2018, it does not shine tau neutrino signals somewhere (by tau airshowers in AUGER, TA, ASHRA or double bang in IceCube) there are a list of consequences to face. These missing correlations and in particular the tau signature absence force us to claim : No Tau? No neutrino Astronomy.
