TeV到PeV能區的微中子天文學

Abstract

利用大氣微中子的天頂角異向性及高天頂角度區及低天頂角度區簇射數目比來探求 銀河系外微中子來源和判段實際大氣prompt微中子的粒子模型

We examine the prompt and conventional atmospheric neutrino fluxes where different models for the prompt flux are employed. Due to different angular dependencies between the prompt flux and the conventional ones, we compare the shower event ratio due to the prompt flux to that due to the conventional flux. This is important to separate the prompt atmospheric neutrino flux from the conventional component. The determination of the former is useful for testing the models for charm productions.
