天體微中子與宇宙線起源之微中子流量比較

The comparison of neutrino flux from astrophysical sources and that from GZK interactions.

指導教授 : 林貴林

摘要


非常高能量的微中子是由天體和宇宙線起源而來。不同的微中子來源會導致不同的微中子味比例。本論文中,我們在不同能量範圍下比較GRB微中子流量和GZK微中子流量,藉由計算這兩個來源積分而來的流量比例,作為選擇微中子閾值能量的方法。我們提出一個統計方法,由微中子望遠鏡的味量測去重建微中子流量的比例。

Very high energy neutrinos come from astrophysical sources and GZK interactions. Different neutrino sources produce different neutrino flavor ratios. In this thesis, we compare GRB neutrino flux with GZK neutrino flux in different energy ranges. The ratio between integrated neutrinos fluxes from these two sources are calculated as a function of chosen neutrino threshold energy. We propose a statistical method to reconstruct such a ratio from flavor measurements of neutrino telescopes.
