BE1: Search for the Higgs boson in associated production
The missing particle of the electroweak standard model is the Higgs boson which shall be responsible for the mass of all observed fundamental particles. Due to this a Higgs will be preferentially be radiated off the heavy particles and will mainly decay into the heaviest kinematically possible particles, for example light Higgs bosons into b quark pairs). Since such quark pairs are produced at high rate by QCD processes, the associated production of the Higgs together with a W or Z boson provides a way out. The latter can be easily identified from thei decay products and, hence, allow for a supression of most background processes [1]. The identification of W or Z bosons uses the leptonic decays of these particles, for example the identification of muons. This analysis aims at a statistically significant discovery of the Higgs boson or the improvement of the exclusion bounds in the mass range of the Higgs boson below about twice the W boson mass. It is the range where the Higgs boson is expected if the standard model is valid.
