A search for evidence of invisible-particle decay modes of a Higgs boson produced in association with a Z boson at the Large Hadron Collider is presented. No deviation from the Standard Model expectation is observed in 4.5 fb$^{-1}$ (20.3 fb$^{-1}$) of 7 (8) TeV pp collision data collected by the ATLAS experiment. Assuming the Standard Model rate for ZH production, an upper limit of 75%, at the 95% confidence level is set on the branching ratio to invisible-particle decay modes of the Higgs boson at a mass of 125.5 GeV. The limit on the branching ratio is also interpreted in terms of an upper limit on the allowed dark matter--nucleon scattering cross section within a Higgs-portal dark matter scenario. Limits are also set on an additional neutral Higgs boson, in the mass range 110<mH<400 GeV, produced in association with a Z boson and decaying to invisible particles.

这封信介绍了在大型强子对撞机上用ATLAS探测器直接搜索质量为110 < m（H）< 130 GeV produced in association with a W or Z boson and decaying to bb. Three decay channels are considered: ZH->llbb，WH->lvbb，ZH->vvbb的标准模型希格斯玻色子的结果，其中l对应于电子或μ子。在ATLAS于2011年收集的对应于4.7/fb的积分亮度的7 TeV pp碰撞数据集中，没有观察到希格斯玻色子产生的证据。在110 - 130 GeV的质量范围内，在95%的置信水平下，希格斯玻色子产生的排除极限为标准模型截面的2.5至5.5倍。对于相同的质量间隔，预期排除限范围在2.5和4.9之间。
