窥探看不见的希格斯粒子

Spying an invisible Higgs

摘要:

我们调查的潜力,多变量技术,以改善LHC搜索看不见的希格斯衰变弱玻色子融合。我们发现,在未来的运行中,LHC将能够在一年内探测到28%的不可见希格斯粒子宽度,在高光度运行期间探测到3.5%。一个显着的改善,这些估计需要分析的QCD辐射模式下降到10 GeV。这样的分析可以将在高光度运行时的到达率提高到2%。在整个分析过程中,我们采用保守的数据驱动背景测定。

英文摘要:

We investigate the potential of multivariate techniques to improve the LHC search for invisible Higgs decays in weak boson fusion. We find that in the coming runs the LHC will be able to probe an invisible Higgs width of 28% within a year and 3.5% during a high luminosity run. A significant improvement over these estimates requires an analysis of QCD radiation patterns down to 10 GeV. Such an analysis can improve the reach at the high luminosity run to 2%. Throughout our analysis we employ a conservative, data driven background determination.
