摘要
喷注是粒子物理对撞机实验中常见的观测对象.很多物理过程中含有喷注末态,喷注重建对于对撞机信号分析具有重要意义.运用事例产生器产生紧致型直线对撞机上的e+e-→ jj模拟事例,对适用于未来高能轻子对撞机上喷注重建的新型序贯重组算法——瓦伦西亚算法(VLC)进行研究.从末态运动学分布、微扰能量修正、非微扰能量修正、质量修正4方面对瓦伦西亚算法、广义e+e-kt算法与kt算法进行对比分析.可以为喷注算法研究和对撞机上多喷注信号寻找提供有益借鉴.
Abstract
Jet is a common observational object in particle physics collider experiments.For many physics processes,jet often appears in the final state.So jet reconstruction is of great significance for the analysis of the signal at colliders.In this paper,we use an event generator to generate the simula-ted events for process e+e-→jj at the Compact Linear Collider.And then we study the new sequential recombination algorithm suitable for future high energy lepton colliders-Valencia Algorithm(VLC).We have compared and analyzed the performance of Valencia algorithm with those of generalized e+e-kt algo-rithm and k,algorithm in aspects of final state kinematics distributions,perturbation energy correc-tion,non-perturbation energy correction and mass correction,respectively.The findings in this paper is helpful for the researches of jet algorithms and the search for multi-jet signals at colliders.
