Combined Upper Limits on Standard Model Higgs Boson Production from the DØ Experiment in 1 . 0 - 2 . 3 fb −

چکیده

Searches for standard model Higgs boson production in p¯ p collisions at √ s = 1.96 TeV have been carried out for Higgs boson masses (mH) in the range 105 < mH < 200 GeV/c 2. Analyses are conducted with integrated luminosities from 1.0 fb −1 to 2.3 fb −1. As no significant excess is observed, we proceed to set limits on standard model Higgs boson production. The observed 95% confidence level upper limits are found to be a factor of 6.4 (2.2) higher than the predicted standard model cross section at mH =115 (160) GeV/c 2 while the expected limits are found to be a factor of 5.5 (2.4) higher than the standard model cross section for the same masses.

Combined Upper Limits on Standard - Model Higgs - Boson Production from the DØ Experiment

Upper limits on the cross section for Standard Model Higgs-boson production in p¯ p → H + X at √ s = 1.96 TeV are determined for 100 < mH < 200 GeV/c 2. The contributing production processes include associated production (W H → νb ¯ b, ZH → /ννb ¯ b) and gluon fusion (H → W + W −). Analyses are conducted with integrated luminosities from 0.84 fb −1 to 1.05 fb −1 recorded by the DØ experiment. L...
