The highest priority of Particle Physics nowadays is to detect the Higgs boson. The discovery of the Higgs is one of the main justifications for constructing the Large Hadrons Collier (LHC) in Europe and for the upgrade of the Everton collier in the USA. Measurements at CERN's LEP collier and the Everton prefer a light Higgs mass. A light Higgs decays dominantly into bottom (b) quarks. Due to the overwhelming background from other processes, it is hard to extract a Higgs signal in bottom final states. Unfortunately the rate of these background events is so high that b events and Higgs candidates are lost before they are even recorded. A solution is to select b events as early as possible. This project proposes to develop an "on-line" b selection algorithm. The development will be done at the working experiment, DO at the Everton. With the knowledge collected in such a study it will be possible to test if this solution can also be applied to the ATLAS detector at the LHC. The proposed project will significantly enhance the Higgs finding potential. It will be carried out at the research institute NIKHEF that has expert knowledge in silicon trackers (used for the tag of b quarks) and is member of both the DO and ATLAS collaborations.
