Hang Zhao, Yong-Feng Zhu, Cheng-Dong Fu, Dan Yu, Man-Qi Ruan

摘要:

作为希格斯粒子工厂的CEPC(Circular Electron-Positron Collider)计划旨在精确测量希格斯玻色子的性质。一个基线探测器概念,APODIS(一个PFA定向探测器的HIggS工厂),已提出了CEPC CDR(概念设计报告)研究。我们探索在这个基线设置与nunuHiggs事件的希格斯签名。带电粒子、光子和喷流的探测性能分别用Higgs → mumu、gamma和jet终态来量化。重建的希格斯玻色子玻色子质量的准确性是可比的,在不同的衰变模式与喷流的最终状态。我们还分析了希格斯-> WW* 和ZZ* 衰变模式,其中观察到不同衰变级联之间的明显分离。

英文摘要:

As a Higgs factory, The CEPC (Circular Electron-Positron Collider) project aims at the precise measurement of the Higgs boson properties. A baseline detector concept, APODIS (A PFA Oriented Detector for the HIggS factory), has been proposed for the CEPC CDR (Conceptual Design Report) study. We explore the Higgs signatures at this baseline setup with nunuHiggs events. The detector performance of the charged particles, the photons, and the jets are quantified with Higgs -> mumu, gammagamma, and jet final states respectively. The accuracy of reconstructed Higgs boson mass is comparable at different decay modes with jets in the final states. We also analyze the Higgs -> WW* and ZZ* decay modes, where a clear separation between different decay cascades is observed.
