Extraction of top backgrounds in the Higgs boson search with the H→WW(*)→ℓℓ+ETmiss decay with a full-jet veto at the LHC
Abstract
The search for a standard model Higgs boson with the H→WW(*)→ℓℓ+ETmiss decay and the application of a full-jet veto yields a strong sensitivity in the mass range 130<mH<200GeV. One of the residual backgrounds is related to processes involving top quarks. A method for the extraction of top backgrounds is evaluated at the parton and hadronic levels based on the data-driven extraction of the jet veto survival probability. The dominant systematic uncertainty of the proposed method is estimated to be about 15%.
