A search for the standard model Higgs boson is presented using events with two charged leptons and large missing transverse energy selected from 5.4 fb(-1) of integrated luminosity in pp collisions at square root(s) = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron collider. No significant excess of events above background predictions is found, and observed (expected) upper limits at 95% confidence level on the rate of Higgs boson production are derived that are a factor of 1.55 (1.36) above the predicted standard model cross section at m(H) = 165 GeV.
使用来自费米实验室 Tevatron 对撞机的 D0 探测器在质心系能量为 1.96 TeV 的 pp 碰撞中采集的 5.4 fb-1 积分亮度下,选取具有两个带电轻子和大的横向能量缺失的事例,对标准模型希格斯玻色子进行了搜索。未发现超出背景预测的显著事例增多,并且在 95%置信水平下,对希格斯玻色子产生率的观测(预期)上限值比 m(H) = 165 GeV 时标准模型预测截面高出 1.55(1.36)倍。
