关于确定由ANITA探测器观测到的UHECR的能量
Towards Determining the energy of the UHECRs observed by the ANITA detector
摘要:
南极脉冲瞬变天线(Antarctic Impulsive Transient Antenna,ANITA)是一个气球载无线电实验,旨在发现超高能宇宙中微子。ANITA探测器已经完成了一个原型和两次在南极大陆上空的全尺寸飞行。在第一次全尺寸飞行期间观测到了两次直接和14次反射的超高能宇宙射线事件,在第二次飞行中观测到了其他几次事件。我们提出了一个蒙特卡罗技术和分析开发,以确定从ANITA数据的初级宇宙线粒子的能量。
英文摘要:
The Antarctic Impulsive Transient Antenna (ANITA) is a balloon-borne radio experiment designed to discover ultra-high energy cosmic neutrinos. The ANITA detector has completed one prototype and two full-scale flights above the Antarctic continent. Two direct and fourteen reflected cosmic ray events of ultra-high energy were observed during the first full scale flight and several others in the second flight. We present a Monte Carlo technique and analysis developed to determine the energy of the primary cosmic ray particles from the ANITA data.
