论文摘要
在本文中，一种用于重建和识别强发腐烂的$τ^+τ^ - $对带有大型Lorentz的增压的新技术，被称为Di-$τ$ Tagger，是在大型Hadron Collider的Atlas实验中首次开发的。搜索共鸣式Higgs玻色子对生产中采用了基准di- $τ$标记选择，其中一个希格斯玻色子腐烂了一个增强的$ b \ bar {b} $ pair，另一个陷入了增强的$τ^+τ^+τ^ - $ pair，并带有两个放射型$τ$τ$ -USTONS的$ -LET-LECTONS。使用139 fb $^{ - 1} $的质子$ - $质子碰撞数据记录在13 tev的质量质量能量中，确定了di- $τ$ tagger的效率，并且估计用Quark-或Gluon-Iniventied Jets误识别为DI-$τ$对象的背景。使用同一数据集在质量范围1 $ -3 TEV进行了搜索通过Gluon $ - $ Gluon Fusion产生的沉重，狭窄的标量共振，并腐烂成两个Higgs玻色子。没有观察到与标准模型预测的偏差，并且在该模型上设置了95％的置信度排除限制。
In this paper, a new technique for reconstructing and identifying hadronically decaying $τ^+τ^-$ pairs with a large Lorentz boost, referred to as the di-$τ$ tagger, is developed and used for the first time in the ATLAS experiment at the Large Hadron Collider. A benchmark di-$τ$ tagging selection is employed in the search for resonant Higgs boson pair production, where one Higgs boson decays into a boosted $b\bar{b}$ pair and the other into a boosted $τ^+τ^-$ pair, with two hadronically decaying $τ$-leptons in the final state. Using 139 fb$^{-1}$ of proton$-$proton collision data recorded at a centre-of-mass energy of 13 TeV, the efficiency of the di-$τ$ tagger is determined and the background with quark- or gluon-initiated jets misidentified as di-$τ$ objects is estimated. The search for a heavy, narrow, scalar resonance produced via gluon$-$gluon fusion and decaying into two Higgs bosons is carried out in the mass range 1$-$3 TeV using the same dataset. No deviations from the Standard Model predictions are observed, and 95% confidence-level exclusion limits are set on this model.
