來自伽瑪射線爆之微中子

Abstract

本論文研究來自伽瑪射線爆的微中子其流量以及味組成，首先考慮典型的伽瑪射線爆。其次計算不同磁場大小對微中子流量以及味組成的影響，並探討流量以及味分布以及與不同光學能譜之伽瑪射線爆之關連性。我們主要探討是否有純粹由中子衰變的微中子流。動機來自於Mohara and Gupta發表的研究。我們的結果將與Mohara此篇作比較。

In this thesis we predict the neutrino flux and flavor composition from gamma-ray bursts (GRBs). At first we consider typical gamma-ray bursts. We calculate the magnetic field effects on GRBs with different magnetic field strength. We also consider the flux and flavor composition dependencies on photon spectra indices for different gamma ray bursts. We aim to look for a pure neutron beam. This thesis is motivated by a study by Moharana and Gupta. We compare our result with that of Moharana and Gupta.
