Abstract
We present a search for the Higgs boson in the process qq̄→ ZH→ℓ+ℓ-bb̄. The analysis uses an integrated luminosity of 1fb-1 of pp̄ collisions produced at s=1.96TeV and accumulated by the upgraded Collider Detector at Fermilab (CDF II). We employ artificial neural networks both to correct jets mismeasured in the calorimeter and to distinguish the signal kinematic distributions from those of the background. We see no evidence for Higgs boson production, and set 95% C.L. upper limits on σZHB(H→bb̄), ranging from 1.5 to 1.2 pb for a Higgs boson mass (mH) of 110 to 150GeV/c2. © 2008 The American Physical Society.
