弱玻色子聚变有望成为大型强子对撞机中中等质量标准模型希格斯玻色子的丰富来源。在这些事件中额外的非常有能量的前喷流提供了强大的背景抑制工具。我们分析了 130-200 GeV 范围内希格斯玻色子质量的 H -> W^(*)W^(*) -> e mu pTmiss 衰变模式。对主要背景的部分子级分析（与喷流相关的 W 对、tt~ 和 Z -> tau tau 的产生）表明，该通道允许在几乎无背景的环境中观察 H -> W^(*)W^(*)，产生集成光度为 5 fb^-1 或更小的显着希格斯玻色子信号。弱玻色子融合实现了比包容性 H -> e mu pTmiss 更好的信号背景比，因此是 130-200 GeV 质量范围内最有前途的搜索通道。
Weak boson fusion promises to be a copious source of intermediate mass Standard Model Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the H -> W^(*)W^(*) -> e mu pTmiss decay mode for a Higgs boson mass in the 130-200 GeV range. A parton level analysis of the dominant backgrounds (production of W pairs, tt~ and Z -> tau tau in association with jets) demonstrates that this channel allows the observation of H -> W^(*)W^(*) in a virtually background-free environment, yielding a significant Higgs boson signal with an integrated luminosity of 5 fb^-1 or less. Weak boson fusion achieves a much better signal to background ratio than inclusive H -> e mu pTmiss and is therefore the most promising search channel in the 130-200 GeV mass range.
