A search is presented for heavy-quark pair production (QQbar) under the decay hypothesis QQbar to WqWq with q = u,d,c,s,b. The search is performed with 1.04 fb^-1 of integrated luminosity from pp collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the CERN LHC. Dilepton final states are selected, requiring large missing transverse momentum and at least two jets. Mass reconstruction of heavy quark candidates is performed by assuming that the W boson decay products are nearly collinear. The data are in agreement with Standard Model expectations; a heavy quark with mass less than 350 GeV is excluded at 95% confidence level.

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。
