Abstract

We present a search for standard model (SM) Higgs boson production using pp collision data at square root(s) = 1.96 TeV, collected with the CDF II detector and corresponding to an integrated luminosity of 4.8 fb(-1). We search for Higgs bosons produced in all processes with a significant production rate and decaying to two W bosons. We find no evidence for SM Higgs boson production and place upper limits at the 95% confidence level on the SM production cross section (sigma(H)) for values of the Higgs boson mass (sigma(H)) in the range from 110 to 200 GeV. These limits are the most stringent for m(H) > 130 GeV and are 1.29 above the predicted value of sigma(H) for c = 165 GeV.

摘要

我们展示了使用 CDF II 探测器在 sqrt(s) = 1.96 TeV 下收集的 pp 碰撞数据对标准模型（SM）希格斯玻色子产生的搜索结果，该数据对应于 4.8 fb(-1) 的积分亮度。我们搜索了所有具有显著产生率并衰变为两个 W 玻色子的希格斯玻色子产生过程。我们没有发现 SM 希格斯玻色子产生的证据，并在 95%置信水平下对 SM 产生截面（sigma(H)）施加了上限，其希格斯玻色子质量（sigma(H)）范围为 110 至 200 GeV。对于 m(H) > 130 GeV，这些限制是最严格的，比 c = 165 GeV 时 sigma(H)的预测值高 1.29。
