摘要：This paper reports searches for the low mass Standard Model Higgs boson through the decay channel H !b¯b. The searches use data up to an integrated luminosity of 5.7fb−1 accumulated in the CDF II detector. To achieve maximal sensitivity on the Higgs boson discovery, we analyze many channels: WH !`n b¯b, ZH !nn b¯b, ZH !``b¯b, andWH/ZH/VBF ! j jb¯b. To further improve the sensitivity of the analyses, discrimination between the Higgs boson signal and the large background is improved by employing sophisticated multivariate techniques. The number of observed events and resulting multivariate output distributions are consistent with the Standard Model expectations, and we set 95% confidence level (C.L.) upper limits on cross section of each process.
