ILC中Higgs分支分数的研究

Higgs Branching Fraction Study in ILC

Hiroaki Ono, Akiya Miyamoto

摘要:

精确测量希格斯玻色子玻色子的性质是国际直线对撞机(ILC)计划的重要内容,它有助于理解与希格斯玻色子玻色子耦合密切相关的粒子质量产生机制。大型强子对撞机(LHC)的实验排除了预测的希格斯质量区域的大面积,他们的结果表明,希格斯玻色子玻色子质量将是轻的。即使LHC在2012年底发现了类Higgs粒子,ILC对Higgs玻色子性质的高精度测量也将证实Higgs粒子的存在,同时Higgs粒子的测量也将验证标准模型(SM)的正确性或为SM的超越提供一些线索。在这项研究中,我们评估的Higgs分支分数的H->bb,cc和gg的质心能量为250和350 GeV的测量精度。

英文摘要:

Precise measurement of the Higgs boson properties are important issues for the International Linear Collider (ILC) project to understand the particles mass generation mechanism which strongly related to the coupling with the Higgs boson. Large Hadron Collider (LHC) experiments exclude the large area of the predicted Higgs mass region and their results indicate that Higgs boson mass will be light. Even if LHC discovers the Higgs like particle by the end of 2012, Higgs will be identified by the high precision measurement of the Higgs boson properties in ILC and also Higgs measurement verifies the correctness of standard model (SM) or gives some hints toward its beyond. In this study, we evaluate the measurement accuracies of Higgs branching fraction to the H->bb, cc and gg at the center-of-mass energy of 250 and 350 GeV.
