Abstract
We present a search for a Higgs-like particle ϕ decaying into bˉb produced in association with b quarks in pˉp collisions. The event sample corresponds to 5.4 fb−1 of integrated luminosity collected with the CDF II detector at the Tevatron collider using a single b tagged jet trigger. We search for an enhancement in the mass of the two leading jets in event with at least three jets identified as coming from b quarks. A data-driven procedure is applied to estimate the dijet mass spectrum of the non-resonant multijet background, which has been used to measure the production cross-section of the Z decaying into bˉb in the same sample but with at least two b-jets. We set one of the most stringent upper limits on σ(pˉp→ϕb)×B(ϕ→bˉb) in the 100−300 GeV/c2 mass range.
