Search for a low-mass standard model Higgs boson in the tt decay channel in pp¯ collisions at vs=1.96TeV

Abstract: We report on a search for the standard model Higgs boson decaying into pairs of ? leptons in p¯p collisions produced by the Tevatron at ?s=1.96??TeV. The analyzed data sample was recorded by the CDFII detector and corresponds to an integrated luminosity of 6.0??fb?1. The search is performed in the final state with one ? decaying leptonically and the second one identified through its semihadronic decay. Since no significant excess is observed, a 95% credibility level upper limit on the production cross section times branching ratio to the ?? final state is set for hypothetical Higgs boson masses between 100 and 150??GeV/c2. For a Higgs boson of 120??GeV/c2 the observed (expected) limit is 14.6 (15.3) the predicted value.
