希格斯粒子在ILC衰变为两个μ子

Higgs decay to two muons at ILC

Michele Faucci Giannelli, Sara Celani

摘要:

希格斯玻色子与第二代粒子的耦合可以通过测量希格斯玻色子衰变为两个μ子来研究。在这项分析中,我们考虑了质量能量为1 TeV的中心的过程,其中WW-fusion过程占主导地位,Higgsstrahlung可以忽略。我们假设积分亮度为500 fb-1,光束偏振度为(Pe- Pe+)=(-0.8,+0.2)。我们使用DBD中描述的ILD探测器的完全模拟来估计希格斯耦合到μ子的灵敏度。我们根据最新的粒子ID工具为两个μ子开发了一个新的选择。灵敏度提高了10%以上。通过利用多变量技术实现了另外10%的增益。结合这两个改进,我们达到了2.7的灵敏度,相对于以前的估计有显着的改善。

英文摘要:

The coupling of the Higgs to second generation particles can be studied by measuring the decay of the Higgs boson to two muons. In this analysis we considered the process at a centre of mass energy of 1 TeV, where the WW-fusion process is dominant and the Higgsstrahlung can be neglected. We assumed an integrated luminosity of 500 fb-1 and a beam polarization of (Pe- Pe+) = (-0.8,+0.2). We estimated the sensitivity of the Higgs coupling to muons using full simulation of the ILD detector described in the DBD. We developed a new selection for the two muons based on the latest available particle ID tools. This improved the sensitivity by more than 10%. A further 10% gains was achieved by exploiting multi variate techniques. Combining the two improvements we reached a sensitivity of 2.7, a significant improvement with respect to the previous estimate.
