摘　　要：在未来的紧致型直线对撞机(CLIC)上,模拟分析标准模型下三规范玻色子WWZ的产生过程。该过程对研究三规范玻色子耦合具有重要意义,也是某些可能的新物理信号的重要背景。具体针对e^(+)e^(-)→W^(+)W^(-)Z→jjjjμ^(+)μ^(-)信号道,在探测器水平下进行了末态运动学分布的研究,还进行了喷注分析,采用为CLIC专门设计的瓦伦西亚喷注算法进行喷注聚类重建,研究不同的喷注半径R值下捕捉到的W喷注的情况。At the future Compact Linear Collider (CLIC),the production process of triboson WWZ in the Standard Model was simulated and analyzed.This process has important significance for the study of triple-gauge-boson coupling and is also an important background for some possible new physics signals.Focusing on the signal channel e~+e~-→W~+W~-Z→jjjjμ~+μ~-,we studied the kinematic distribu‐tions of the final state at the detector level.Furthermore,jet analysis was also carried out.The Valencia jet algorithm specially designed for CLIC was adopted to study the W-jet reconstruction with different jet radii R in jet clustering.
