<jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>A search for the standard model Higgs boson in the H → ZZ → 2<jats:italic>ℓ</jats:italic>2<jats:italic>ν</jats:italic> decay channel, where <jats:italic>ℓ</jats:italic> = e or <jats:italic>μ</jats:italic>, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 fb<jats:sup>−1</jats:sup>. 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 270-440 GeV range is excluded at 95% confidence level.</jats:p>
