Search for the standard model Higgs boson in the H->ZZ->2l2nu decay channel in the CMS Experiment

Abstract

A search for the Standard Model Higgs boson in the H->ZZ->2l2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of both 7 and 8 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 5.0 fb-1 at 7 TeV and 5.0 fb-1 at 8 TeV. The search is optimized separately for the vector boson fusion and the gluon fusion production processes.No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 278-600 GeV/c2 range is excluded at 95% confidence level.
