摘要:

本文研究了经典的$e^+e^-$喷注重建算法、纵向不变算法和最近提出的Valencia算法在$e^+e^-$碰撞中的性能。该研究包括扰动和非扰动射流能量修正和现实背景条件下的响应的比较。在$\sqrt{s}= 3$ ~ \tev上,使用详细的探测器模拟对几种算法进行基准测试。我们发现,经典的$e^+e^-$算法,有或没有光束射流,有最好的响应,但在不可忽略的背景的环境是不够的。Valencia算法和纵向不变的$k_t$算法具有更强的鲁棒性,前者略占优势。

英文摘要:

In this paper we study the performance in $e^+e^-$ collisions of classical $e^+e^-$ jet reconstruction algorithms, longitudinally invariant algorithms and the recently-proposed Valencia algorithm. The study includes a comparison of perturbative and non-perturbative jet energy corrections and the response under realistic background conditions. Several algorithms are benchmarked with a detailed detector simulation at $\sqrt{s}= 3$~\tev. We find that the classical $e^+e^-$ algorithms, with or without beam jets, have the best response, but are inadequate in environments with non-negligible background. The Valencia algorithm and longitudinally invariant $k_t$ algorithms have a much more robust performance, with a slight advantage for the former.
