论文摘要

通过$ b \ bar {b} b \ bar {b} $在ATLAS实验中使用126 fb $^{ - 1}质量proton-proton碰撞数据$ \ sqrt collrt collren collran collran collran coll coll,搜索了通过$ b \ bar {b} b \ bar {b} $在$ b \ bar {b} b \ bar {b} $中搜索Higgs Boson对生产的搜索。这种搜索对VBF的产生敏感,可能会腐烂到希格斯玻色子对,而在非共振拓扑中,它可以限制希格斯玻色子和矢量玻色子之间的四分之一耦合。没有观察到相对于标准模型预期的显着过量,并且在扩展的Higgs部门的背景下,生产横截面的限制设置为95%的置信度,而非共鸣Higgs玻色子对生产。还提供了Higgs Boson对与两个矢量玻色子之间的耦合的解释:将耦合值归一化为$κ__{2V} <-0.43 $和$κ_和$κ__{2V}> 2.56 $的耦合值在95%的置信度中排除在数据中。

A search for Higgs boson pair production via vector-boson fusion (VBF) in the $b\bar{b}b\bar{b}$ final state is carried out with the ATLAS experiment using 126 fb$^{-1}$ of proton-proton collision data delivered at $\sqrt{s} = 13$ TeV by the Large Hadron Collider. This search is sensitive to VBF production of additional heavy bosons that may decay into Higgs boson pairs, and in a non-resonant topology it can constrain the quartic coupling between the Higgs bosons and vector bosons. No significant excess relative to the Standard Model expectation is observed, and limits on the production cross-section are set at the 95 % confidence level for a heavy scalar resonance in the context of an extended Higgs sector, and for non-resonant Higgs boson pair production. Interpretation in terms of the coupling between a Higgs boson pair and two vector bosons is also provided: coupling values normalised to the Standard Model expectation of $κ_{2V} < -0.43$ and $κ_{2V} > 2.56$ are excluded at the 95 % confidence level in data.
