论文摘要
我们提出了一种新的方法，即作为初始状态辐射（ISR）排放的喷气机的Quark-Gluon标记可以从Gluon融合过程中促进对不可减至的Electroweak Vection Vector Boson Productions的搜索。尽管夸克ISR通常比Gluon在背景过程中占据主导地位，主要是频繁通过Quark-Gluon在LHC处引发的硬散射，但Gluon Fusion中的Gluon ISR部分在检测器的中央区域可能会大大更大。通过使用喷气子结构变量捕获新功能的Jet子结构变量，专注于无形的希格斯搜索，我们证明了Gluon Fusion的Higgs限制了隐形Higgs衰减最大，过于传统上是最限制的矢量玻色子融合，并且对分支比率的限制得到了显着提高。我们总结强调，我们的方法在寻找Gluon融合过程的新共鸣方面具有更广泛的含义。
We propose a novel method in that quark-gluon tagging of the jets emitted as initial state radiation (ISR) can boost searches of invisible Higgs from gluon fusion processes against irreducible electroweak vector boson productions. While quark ISR typically takes up a dominant portion than gluon in the background processes mainly by frequent quark-gluon initiated hard scatterings at the LHC, gluon ISR portion in the gluon fusion can be significantly larger in the central region of detector. Focusing on invisible Higgs searches using jet substructure variables capturing the new features, we demonstrate that Higgs from gluon fusion constrains invisible Higgs decays the most, over vector boson fusion traditionally known as the most constraining, and the limit on the branching ratio is significantly improved. We summarize with emphasizing that our method has wider implications in search for new resonances from gluon fusion processes.
