The Higgs boson couplings to bottom and top quarks have been measured and agree well with the Standard Model predictions. Decays to lighter quarks and gluons, however, remain elusive. Observing these decays is essential to complete the picture of the Higgs boson interactions. In this work, we present the perspectives for the 14 TeV LHC to observe the Higgs boson decay to gluon jets assembling convolutional neural networks, trained to recognize abstract jet images constructed embodying particle flow information, and boosted decision trees with kinetic information from Higgs-strahlung ##IMG## [http://ej.iop.org/images/2632-2153/1/4/045025/mlstaba8e6ieqn1.gif] {$ZH\to \ell^{+}\ell^{-} + gg$} events. We show that this approach might be able to observe Higgs to gluon decays with a significance of around 2.4 σ improving significantly previous prospects based on cut-and-count analysis. An upper bound of BR ( H → gg )≤1.74 × BR ...

迈向认识希格斯玻色子的亮面

已经测量了希格斯玻色子与上下夸克的耦合，并与标准模型的预测非常吻合。然而，较轻的夸克和胶子的衰减仍然难以捉摸。观察这些衰减对于完成希格斯玻色子相互作用的图像至关重要。在这项工作中，我们提出了14 TeV LHC的观点，以观察希格斯玻色子对组装了卷积神经网络的胶子射流的衰变，经过训练以识别体现粒子流信息的抽象射流图像，并利用希格斯-斯特拉伦的动力学信息增强决策树## IMG ## [http://ej.iop.org/images/2632-2153/1/4/045025/mlstaba8e6ieqn1.gif] {$ ZH \至\ ell ^ {+} \ ell ^ {-} + gg $}个事件。我们表明，这种方法可能能够观察到希格斯到胶子衰变，其重要性约为2。4σ基于切入量分析，显着改善了先前的前景。BR（H→gg）的上限≤1.74×BR ...
