用ATLAS探测器在$\sqrt{s}$ = 13 TeV的PDMATHAAB碰撞中寻找希格斯玻色子在$b\bar{b}b\bar{b}$末态的共振对产生

Search for resonant pair production of Higgs bosons in the $b\bar{b}b\bar{b}$ final state using $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

ATLAS Collaboration

摘要:

研究了在$b\bar{b}b\bar{b}$末态中产生共振Higgs玻色子对的可能性。分析使用126-139 fb $^{-1}$的$pp$碰撞数据在$\sqrt{s}$ = 13 TeV收集的ATLAS探测器在大型强子对撞机。分析分为两个通道,针对希格斯玻色子衰变重建为对小半径的射流或作为个人的大半径的射流。自旋0和自旋2的基准信号模型被认为是,这两个对应于共振$HH$生产通过胶子$-$胶子融合。这些数据与标准模型的预测一致。上限的生产截面倍分支比希格斯玻色子对一个新的共振的质量范围从251 GeV到5 TeV。

英文摘要:

A search for resonant Higgs boson pair production in the $b\bar{b}b\bar{b}$ final state is presented. The analysis uses 126-139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond to resonant $HH$ production via gluon$-$gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross-section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV.
