我们报告了利用费米实验室 Tevatron 对撞机的 D0 探测器记录的积分光度，在缺失能量和共面射流拓扑中寻找标准模型希格斯玻色子的过程。分析包括来自生产的信号贡献，以及来自生产的信号贡献，其中来自玻色子衰变的带电轻子未被检测到。神经网络用于将信号与背景分离。在没有信号的情况下，我们将限制设置为 95% C.L.。 2.6–2.3 pb，希格斯玻色子质量在 105–135 GeV 范围内，其中，。相应的预期限值范围为 2.8 至 2.0 pb。
We report a search for the standard model Higgs boson in the missing energy and acoplanar-jet topology, using an integrated luminosity ofrecorded by the D0 detector at the Fermilab TevatronCollider. The analysis includes signal contributions from, as well as fromproduction in which the charged lepton from theboson decay is undetected. Neural networks are used to separate signal from background. In the absence of a signal, we set limits onat the 95% C.L. of 2.6–2.3 pb, for Higgs boson masses in the range 105–135 GeV, where,. The corresponding expected limits range from 2.8 to 2.0 pb.
