论文摘要
在本文中，我们提出了一种六角形描述，以实现超富型（UHE）中微子和抗毒剂的风味组成，希望可以在未来的大型中微子望远镜上确定。有了这样的几何描述，我们能够清楚地将中微子的单个风味组成与一个常规的六角形中的抗肿性分离，这可以看作是广泛使用的三元图的自然概括。为了进行说明，我们将$ pp $或$pγ$碰撞视为宇宙加速器中UHE中微子和抗肿瘤的主要生产机制，并研究了标准图片中的中微子振荡如何以及在lindblad eTohence的存在下如何改变中微子和抗抗原剂的味道。
In this paper, we propose a hexagonal description for the flavor composition of ultrahigh-energy (UHE) neutrinos and antineutrinos, which will hopefully be determined at the future large neutrino telescopes. With such a geometrical description, we are able to clearly separate the individual flavor composition of neutrinos from that of antineutrinos in one single regular hexagon, which can be regarded as a natural generalization of the widely-used ternary plot. For illustration, we consider the $pp$ or $pγ$ collisions as the dominant production mechanism for UHE neutrinos and antineutrinos in the cosmic accelerator, and investigate how neutrino oscillations in the standard picture and in the presence of Lindblad decoherence could change the flavor composition of neutrinos and antineutrinos at neutrino telescopes.
