粒子流量热法的研究进展

Progress with Particle Flow Calorimetry

M. A. Thomson

摘要:

ILC对探测器最重要的要求之一是良好的喷流能量分辨率。人们普遍认为,量热的粒子流方法是实现ILC目标的关键,即双射流不变质量分辨率sigma_m/m < Gamma_Z/m_Z。本文介绍了目前的PandoraPFA粒子流算法的性能。对于在Tesla TDR探测器上模拟的轻夸克喷注,在45-250 GeV喷注能量范围内,得到的喷注能量分辨率优于sigma_E/E ~ 3.4%。这代表了粒子流量热法可以达到ILC射流能量分辨率目标的第一个证明。

英文摘要:

One of the most important requirements for a detector at the ILC is good jet energy resolution. It is widely believed that the particle flow approach to calorimetry is the key to achieving the ILC goal of a di-jet invariant mass resolution sigma_m/m < Gamma_Z/m_Z. This paper describes the current performance of the PandoraPFA particle flow algorithm. For simulated light quark jets in the Tesla TDR detector, the jet energy resolution achieved is better than sigma_E/E ~ 3.4% for jet energies in the range 45-250 GeV. This represents the first demonstration that Particle Flow Calorimetry can reach the ILC jet energy resolution goals.
