Higgs boson search in the H->ZZ{sup (*)} decay channels with the CMS detector
- University of Split, Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture, Split (Croatia)
A study of the sensitivity for the inclusive production of Standard Model Higgs bosons H decaying in ZZ{sup (*)} pairs is presented with the CMS experiment at the CERN LHC pp collider at 14 TeV centre of mass energy, for the integrated luminosity of 1 fb{sup -1}. The analysis is performed for the leptonic decay channels H->ZZ{sup (*)}->4l with l = e,mu and for a mass m{sub H} in the range from 120 to 250 GeV/c{sup 2}. A simple m{sub H} independent sequence of cuts is established which provides a clean sample of 4l events while preserving the highest signal detection efficiency. A signal with a significance above 2 standard deviations is found unlikely for a Higgs boson with a mass m{sub H} lying anywhere in the mass range considered. In absence of significant deviations from background expectations, upper limits on the production cross-section of a Standard Model-like Higgs boson can be established. The limits extend beyond existing constraints.
