超高能中微子流作为大额外维的探测器

Ultrahigh-energy neutrino flux as a probe of large extra-dimensions

Joseph Lykken, Olga Mena, Soebur Razzaque

摘要:

在额外维度的情况下,超高能(UHE,>= 10^{18} eV)中微子的光谱将受到抑制,这是由于超新星遗迹中微子的中微子-反中微子湮灭过程增强。在n>4的情况下,n是额外维度的数量,中微子不能对UHE宇宙线谱中观察到的最高能量事件负责。这些额外维度的相互作用的直接暗示是在正在进行的和未来的中微子望远镜中没有UHE中微子。

英文摘要:

A suppression in the spectrum of ultrahigh-energy (UHE, >= 10^{18} eV) neutrinos will be present in extra-dimensional scenarios, due to enhanced neutrino-antineutrino annihilation processes with the supernova relic neutrinos. In the n>4 scenario, being n the number of extra dimensions, neutrinos can not be responsible for the highest energy events observed in the UHE cosmic ray spectrum. A direct implication of these extra-dimensional interactions would be the absence of UHE neutrinos in ongoing and future neutrino telescopes.
