CEPC研究报告:希格斯粒子物理分析

CEPC Research Report: Higgs Physics Analysis

Manqi Ruan, Yaquan Fang, Gang Li, Dan Yu

摘要:

2018年11月,CEPC发布了概念设计报告(CDR),其中包括物理潜力调查和对不同探测器概念的分析。从那时起,CEPC对希格斯物理的深入研究取得了进展。同时也考虑了在最高阈值处的运行,并研究了质心能量为360 GeV附近的物理势。$ttH$通道信息使240 GeV的Higgs粒子宽度测量精度提高了2倍。在CEPC的Higgs工厂中,在质心能量为240 GeV的条件下,分析了Higgs到b/c/g和Higgs到$ττ$的不同衰变模式,改进了Higgs的测量。先进的分析技术,如喷注重建和喷注中轻子的识别等,在喷注分析中得到了发展和应用。正在制定新的解释,以改善业绩。

英文摘要:

In November 2018, the CEPC released the Conceptual Design Report (CDR) with the physics potential investigation and the analysis about different detector concepts. Since then, intensive researches on the Higgs Physics at the CEPC have been progressed. The run at top thresholds are also taken into consideration and the physics potential around the center-of-mass energy of 360GeV is studied. The $ttH$ channel information boost the precision of Higgs width measurement by a factor of 2 with respect to 240 GeV Higgs Runs. Different Higgs decay modes are analyzed in the CEPC Higgs factory at the center-of-mass energy of 240GeV, including Higgs to b/c/g and Higgs to $ττ$, which improves the Higgs measurement. Advanced analysis technologies are developed and applied in the analysis, such as jet reconstruction and lepton identification in jets. New interpretations are under developing to improve the performance.
