在CLIC上测量Higgs Yukawa与b、c夸克和μ子耦合的前景

Prospects for the Measurement of the Higgs Yukawa Couplings to b and c quarks, and muons at CLIC

Christian Grefe, Tomas Lastovicka, Jan Strube

摘要:

对希格斯玻色子性质的研究,特别是对预测的分支比与终态质量的线性相关性的测试,将是可预见的未来能量前沿对撞机物理计划的一个组成部分。在3 TeV CLIC机器上的大希格斯玻色子产生截面允许精确测量希格斯分支比。假设积分亮度为2 ab-1,测量了质量为120 GeV的标准模型希格斯玻色子衰变H->bb,H->cc和H->μμ的截面乘以分支比,其统计不确定度分别为0.23%,3.1%和15%.

英文摘要:

The investigation of the properties of the Higgs boson, especially a test of the predicted linear dependence of the branching ratios on the mass of the final state is going to be an integral part of the physics program at colliders at the energy frontier for the foreseeable future. The large Higgs boson production cross section at a 3TeV CLIC machine allows for a precision measurement of the Higgs branching ratios. The cross section times branching ratio of the decays H->bb, H->cc and H->μμ of a Standard Model Higgs boson with a mass of 120 GeV can be measured with a statistical uncertainty of 0.23%, 3.1% and 15%, respectively, assuming an integrated luminosity of 2 ab-1.
