高能中微子天文学

High Energy Neutrino Astronomy

V. Berezinsky

摘要:

超高能中微子理论的简要回顾。讨论了超新星遗迹、伽马射线暴、活动星系核等加速源。自上而下的来源包括拓扑缺陷(TD),超重暗物质(SHDM)和镜像物质。扩散通量被认为是宇宙成因和自上而下的中微子。根据费米-LAT的高能γ辐射扩散数据,对中微子扩散通量的级联上限进行了研究。这是最普遍和严格的上限,适用于宇宙起源和自上而下的模型。目前,许多探测器的上限接近级联上限,5年冰立方上限将远低于它。

英文摘要:

The short review of theoretical aspects of ultra high energy (UHE) neutrinos. The accelerator sources, such as Supernovae remnants, Gamma Ray Bursts, AGN etc are discussed. The top-down sources include Topological Defects (TDs), Superheavy Dark Matter (SHDM) and Mirror Matter. The diffuse fluxes are considered accordingly as that of cosmogenic and top-down neutrinos. Much attention is given to the cascade upper limit to the diffuse neutrino fluxes in the light of Fermi-LAT data on diffuse high energy gamma radiation. This is most general and rigorous upper limit, valid for both cosmogenic and top-down models. At present upper limits from many detectors are close to the cascade upper limit, and 5 yr IceCube upper limit will be well below it.
