Search for the standard model Higgs boson produced in association with top quarks using the full CDF data set

A search is presented for the standard model Higgs boson produced in association with top quarks using the full Run II proton-antiproton collision data set, corresponding to 9.45fb -1, collected by the Collider Detector at Fermilab. No significant excess over the expected background is observed, and...

Sumario:A search is presented for the standard model Higgs boson produced in association with top quarks using the full Run II proton-antiproton collision data set, corresponding to 9.45fb -1, collected by the Collider Detector at Fermilab. No significant excess over the expected background is observed, and 95% credibility-level upper bounds are placed on the cross section σ(ttÌ„H→lepton+missing transverse energy+jets). For a Higgs boson mass of 125GeV/c2, we expect to set a limit of 12.6 and observe a limit of 20.5 times the standard model rate. This represents the most sensitive search for a standard model Higgs boson in this channel to date. © 2012 American Physical Society.
