μ子电磁簇射重建算法

Algorithm for muon electromagnetic shower reconstruction

S. Mangano

摘要:

ANTARES中微子望远镜目前正在地中海2500米深处建造。该实验的主要目的是探测高能宇宙μ子中微子,它们由带电电流相互作用中产生的μ子识别。这些μ子是通过测量它们发出的穿过探测器的切伦科夫光来探测的。有时高动量μ介子会产生电磁簇射。本文的主题是一种方法来重建这些簇射,其中包括几个步骤:一个算法的μ子轨道参数的拟合,预选探测到的光子属于簇射,并与预选探测到的光子计算电磁簇射位置的最终拟合。最后,与该部分的检测器,目前正在运行和模拟获得的数据之间的比较。

英文摘要:

The ANTARES neutrino telescope is presently being built in the Mediterranean Sea at a depth of 2500 m. The primary aim of the experiment is the detection of high energy cosmic muon neutrinos, which are identified by the muons that are produced in charged current interactions. These muons are detected by measuring the Cerenkov light which they emit traversing the detector. Sometimes a high momentum muon produces electromagnetic showers. The subject of this paper is a method to reconstruct these showers which includes several steps: an algorithm for the fit of the muon track parameters, preselection of detected photons belonging to a shower, and a final fit with the preselected detected photons to calculate the electromagnetic shower position. Finally a comparison between data obtained with that part of the detector that is currently in operation and simulations is presented.
