h-> mu^+ mu^- via tth在LHC的生产

h-> mu^+ mu^- via tth Production at the LHC

Shufang Su, Brooks Thomas

摘要:

在这项工作中,我们研究的过程中,在大型强子对撞机中,一个希格斯玻色子产生与一个t-t-酒吧对,随后衰变为一对μ子。我们表明,在这个通道中发现一个质量约为120 GeV的轻的标准模型希格斯玻色子的统计意义与希格斯衰变为μ子对的其他过程(胶子融合,弱玻色子融合)的统计意义相当。结合所有这三个渠道,我们表明,希格斯玻色子的质量范围为115 GeV < m_h < 130 GeV的证据,可以获得在3西格玛的显着性水平与积分亮度为300 fb^{-1}。我们还计算了在这个通道中发现非标准希格斯玻色子所需的横截面的增强因子。

英文摘要:

In this work, we examine the process at the LHC in which a Higgs boson is produced in association with a t t-bar pair and subsequently decays to a pair of muons. We show that the statistical significance for the discovery of a light, Standard-Model Higgs boson with a mass around 120 GeV in this channel is comparable to those for other processes (gluon fusion, weak-boson fusion) in which the Higgs decays to a muon pair. Combining all three of these channels, we show that evidence for a Higgs boson with a mass in the range 115 GeV < m_h < 130 GeV could be obtained at the 3 sigma significance level with an integrated luminosity of 300 fb^{-1}. We also calculate the enhancement factor to the cross-section that would be needed to discover a non-standard Higgs boson in this channel.
