Combined DØ Upper Limits on Standard - Model Higgs - Boson Production

ثبت نشده
چکیده

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 processes include associated production (W H → νb ¯ b, ZH → + − /ν ¯ νb ¯ b, and W H → W W + W −) and gluon fusion (H → W + W −). Analyses are conducted with integrated luminosities from 260 pb −1 to 950 pb −1 recorded by the DØ experiment. Limits for various combinations of the channels are presented. The results are in good agreement with background expectations and the 95% CL upper limits are found to be a factor of 16.3(4.3) higher than the Standard-Model cross section at mH =115(160) GeV/c 2 .

Combined CDF and DØ Upper Limits on Standard Model Higgs - Boson Production with up

We combine results from CDF and DØ on direct searches for a standard model (SM) Higgs boson (H) in p¯ p collisions at the Fermilab Tevatron at √ s = 1.96 TeV. Compared to the previous Higgs Tevatron combination, more data and new channels (W H → τ νb ¯ b, V H → τ τ b ¯ b/jjτ τ , V H → jjb ¯ b, t ¯ tH → t ¯ tb ¯ b) have been added. Most previously used channels have been reanalyzed to gain sensi...

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

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 up...

Updated Combination of Searches for the Standard Model Higgs Boson at the DØ Experiment in 9 . 7 fb − 1 of Data

Searches for standard model Higgs boson production at the DØ experiment in p¯ p collisions at √ s = 1.96 TeV are carried out for Higgs boson masses (mH) in the range 100 ≤ mH ≤ 200 GeV. Most of these searches use the full Run II data set, corresponding to an integrated luminosity of 9.7 fb −1 , and are combined to maximize the sensitivity to the standard model Higgs boson. In absence of a signi...
