The data have been collected by the Run II DO detector. In order to maximize the sensitivity multivariate techniques such as artificial neural networks (NN), matrix element methods and likelihoods are used. No excess above the Standard Model background is observed and limits on the production cross section times branching ratio for Higgs masses between 115 and 200 GeV are set.Contributed to 42nd Rencontres de Moriond on Electroweak Interactions and Unified Theories, La Thuile, Italy, Mai 2007High Energy Physics - Experimenttext
