TL;DR: In this article, a preliminary investigation of the potential to study the channel Z + b − jet with the Z → μμ at the LHC is presented, first with a fast simulation of the ATLAS detector, and then, using the full simulation and the complete offline reconstruction algorithms in the official ATLAS software framework.
Abstract: The study of Z boson production in association with a single heavy flavor jet (gQ → ZQ(Q = b, c)) can provide interesting insight on the heavy quark content of the proton. In addition, this process represents a background to the search for the Higgs boson, when it is produced together with a b quark and decays in the same final states (bb, τ+τ−, μ+μ−).This paper presents a preliminary investigation of the potential to study the channel Z + b − jet with the Z → μμ at LHC. The expected statistics and purity of the event sample that could be selected in the data are evaluated considering two different methods for the b tagging.The analysis has been performed, first, with a fast simulation of the ATLAS detector, and then, using the full simulation and the complete offline reconstruction algorithms in the official ATLAS software framework.

TL;DR: In this paper, a search for the Higgs boson in the channels at DO is described, corresponding to an integrated luminosity of up to 177 pb-1, compared to theoretical predictions.
Abstract: A search for the Higgs boson in the channels at DO is described. The data, corresponding to an integrated luminosity of up to 177 pb-1, are compared to theoretical predictions. No excess of events above the expected background is observed in any of the leptonic final states. Limits on the production cross-section times branching ratio, σ × BR(H → WW*), are therefore set at the 95% Confidence Level.
