# Search for the Higgs boson in the all-hadronic final state using the CDF II detector

Abstract : We report on a search for the production of the Higgs boson decaying to two bottom quarks accompanied by two additional quarks. The data sample used corresponds to an integrated luminosity of approximately 4 fb${-1}$ of $p\bar{p}$ collisions at \surd s = 1.96 TeV recorded by the CDF II experiment. This search includes twice the data of the previous published result, uses new analysis techniques to distinguish jets originating from light flavor quarks and those from gluon radiation, and adds sensitivity to a Higgs boson produced by vector boson fusion. We find no evidence of the Higgs boson and place limits on the Higgs boson production cross-section for Higgs boson masses between 100 GeV/c$^{2}$ and 150 GeV/c$^{2}$ at 95% confidence level. For a Higgs boson mass of 120 GeV/c$^{2}$ the observed (expected) limit is 10.5 (20.0) times the predicted Standard Model cross-section.
