标题： Simulation of the Event Reconstruction of Ultra High Energy Cosmic Neutrinos with Askaryan Radio Array

摘要： Askaryan射电阵列（ARA），一个科学家提议在南极洲建造的大规模射电切伦科夫观测站，旨在通过观测超高能（UHE）宇宙起源中微子来揭示产生最高能量宇宙射线的宇宙加速器的起源和演化。 为了优化ARA对入射UHE中微子的角度分辨率，这对于指向其源至关重要，研究了ARA的重建能力与其设计之间的关系。 结果表明，在考虑噪声效应的情况下，为了使这种中微子角度分辨率尽可能好且检测效率尽可能高，ARA几何形状的最佳选择将是站间距1.6公里和天线间距40米。 显示英文摘要

摘要： Askaryan Radio Array (ARA), a large-scale radio Cherenkov observatory which scientists propose to develop in Antarctica, aims at discovering the origin and evolution of the cosmic accelerators that produce the highest energy cosmic rays by means of observing the ultra high energy (UHE) cosmogenic neutrinos. To optimize ARA's angular resolution of the incoming UHE neutrinos, which is essential for pointing pack to its source, the relation between the reconstruction capabilities of ARA and its design is studied. It is found that with the noise effect taken into account, in order to make this neutrino angular resolution as good as possible and detection efficiency as high as possible, the optimal choice for ARA geometry would be the station spacing of 1.6 km and the antenna spacing of 40 m.
