A 2D fit with background measurement constraints to boost the Higgs to 4l discovery potential at the LHC
A data-driven method for simultaneously extracting a potential Higgs to ZZ to 4e, 4mu, 2e2mu 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...
