Abstract
A search for the Standard Model (SM) Higgs boson in pp collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 1.6 fb−1 recorded by the CMS experiment. The search is conducted in the decay channel H → ZZ → 2l 2ν . No excess is observed in the transverse mass distributions. Limits are set on the production of the Higgs boson in the context of the Standard Model and in the presence of a sequential fourth family of fermions with high masses.

Summary
The search for the SM Higgs boson and its discovery are central to the goals of the experiments at the LHC. The primary production mechanism of the Higgs at the LHC is gluon fusion with the small contribution from vector boson fusion. This note presents search for SM Higgs boson in the H → ZZ → 2l2ν channel which is sensitive to Higgs searches in the high mass range (250 − 600GeV/c2). The braching fraction of this decay channel is about six times higher than that of golden channel H → ZZ → l−l+l−l+. This may lead to better sensitivity to SM Higgs boson production at higher masses, where background can be effectively suppressed kinematically
