Abstract
A data-driven method for simultaneously extracting a potential Higgs → ZZ(∗) → 4e, 4μ, 2e2μ signal and its dominant backgrounds, is presented. The method relies on a combined fit of the 2-lepton, Z(∗), and 4-lepton invariant masses. The fit is assisted by normalization of the Z+X backgrounds in data control regions. The Higgs discovery potential for the next few years of LHC running is presented. The demonstrated high sensitivity of the method makes it ideal for the search performed by the ATLAS and CMS experiments.
