论文摘要

搜索与高能量光子相关的标准模型Higgs玻色子的生产。侧重于矢量 - 玻色子融合过程和主要的希格斯玻色子衰减到$ b $ quark对,与更具包容性搜索相比,搜索受益于多吉特背景的大幅度降低。结果是从$ \ sqrt {s} $ = 13 $ = 13 tev在LHC上收集的132 fb $^{ - 1} $ collision Data的132 fb $^{ - 1} $。该最终签名中测得的希格斯玻色子信号产量为$ 1.3 \ pm 1.0 $ $乘以标准模型预测。在背景上方观察到的希格斯玻色子信号的显着性是1.3标准偏差,而预期的显着性为1.0标准偏差。

A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into $b$-quark pairs, the search benefits from a large reduction of multijet background compared to more inclusive searches. Results are reported from the analysis of 132 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$=13 TeV collected with the ATLAS detector at the LHC. The measured Higgs boson signal yield in this final-state signature is $1.3 \pm 1.0$ times the Standard Model prediction. The observed significance of the Higgs boson signal above the background is 1.3 standard deviations, compared to an expected significance of 1.0 standard deviations.
