Finding H0 ---> b anti-b at the LHC

We have investigated the sensitivity of CMS for finding the Higgs boson in the H0 -> bbbar channel. An excellent b-tagging performance and a good jet resolution are the main requirements needed for a successful event selection. In the Standard Model (SM), the ttbar H0 -> l+- nu qqbar bbbar bbbar channel is accessible, if the Higgs mass is lighter than m(H0) = 125 GeV, already during the first years of the LHC. Also, most of the MSSM (Minimal Supersymmetric Standard Model) parameter space can be covered. The W+- H0 -> l+- nu bbbar channel is only accessible with high luminosity at the LHC. In both channels the mass can be determined with a precision of a few per cent and the Higgs couplings at the level of 10%.
