摘要：

我们报告的搜索标准模型希格斯玻色子衰变到$b \bar{b}$在$pp$碰撞在ATLAS和CMS实验。这些依赖于希格斯玻色子与矢量玻色子或顶夸克对结合产生的特征。结果，基于$5.0~\mathrm{fb}^{-1}$的$pp$碰撞数据在$\sqrt{s} = 7$ ~TeV和高达$13.0~\mathrm{fb}^{-1}$的数据在$\sqrt{s} = 8$ ~TeV的LHC加速器收集。这些都表示在95%的置信水平上限的标准模型希格斯玻色子的生产截面乘以分支比衰变到$b$ -夸克对。

英文摘要：

We report on searches for the Standard Model Higgs boson decaying to $b \bar{b}$ in $pp$ collisions at the ATLAS and CMS experiments. These rely on signatures where the Higgs boson is produced in association with a vector boson or in association with a top-quark pair. Results are presented, based on $5.0~\mathrm{fb}^{-1}$ of $pp$ collision data at $\sqrt{s} = 7$~TeV and up to $13.0~\mathrm{fb}^{-1}$ of data at $\sqrt{s} = 8$~TeV collected by the LHC accelerator. These are expressed in terms of 95\% confidence level upper limits on the production cross section of the Standard Model Higgs boson times the branching ratio to decay to $b$-quark pair.
