摘要

We present new results of the search for production in collisions at a center-of-mass energy of , based on a dataset with integrated luminosity of 0.44 fb⁻¹. We combine these new results with previously published searches by the D0 collaboration, for WH and ZH production analyzed in the final state, for ZH () production, for WH (→WWW) production, and for H (→WW) direct production. No signal-like excess is observed either in the WH analysis or in the combination of all D0 Higgs boson analyses. We set 95%C.L. (expected) upper limits on ranging from 1.6 (2.2) pb to 1.9 (3.3) pb for Higgs boson masses between 105 and 145 GeV, to be compared to the theoretical prediction of 0.13 pb for a Standard Model (SM) Higgs boson with mass a20d5fdf181be635a45a" title="Click to view the MathML source" alt="Click to view the MathML source">m_H=115 GeV. After combination with the other D0 Higgs boson searches, we obtain for 46a9ee16fe0f8" title="Click to view the MathML source" alt="Click to view the MathML source">m_H=115 GeV an observed (expected) limit 8.5 (12.1) times higher than the SM predicted Higgs boson production cross section. For m_H=160 GeV, the corresponding observed (expected) ratio is 10.2 (9.0).
