Extraction of Top Backgrounds in the Higgs Boson Search with the $H\to W{W}^{\ast }\to \ell \ell +E_{\mathrm{T}}^{\mathrm{miss}}$ Decay with a Full-Jet Veto at the LHC

Abstract

The search for a Standard Model Higgs boson with the $H\to W{W}^{\ast }\to \ell \ell +E_{\mathrm{T}}^{\mathrm{miss}}$ decay and the application of a full-jet veto yields a strong sensitivity in the mass range $130<m_H<200$ GeV. 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 uncertainty of the proposed method is about 15%.
