Analysis strategy for the SM Higgs boson search in the four-lepton final state in CMS
The current status of the searches for the SM Higgs boson in the
decay channel with the CMS
experiment is presented. The selection cuts for suppressing the backgrounds
while keeping very high signal efficiencies are described, along with the
data-driven algorithms implemented to estimate the background yields and the
systematic uncertainties. With an integrated luminosity of , upper limits at 95% CL on the SM-like Higgs cross section
branching ratio exclude cross sections from about one to two times the
expected value from the Standard Model in the range . No evidence for the existence of the SM Higgs boson has been
found so far.Comment: "Presented at the 2011 Hadron Collider Physics symposium (HCP-2011),
