No evidence of events beyond the background expectation is found. Upper limits on the non-resonant <jats:italic>pp</jats:italic> → <jats:italic>HH</jats:italic> production cross section of 10 pb and on the resonant production cross section as a function of the <jats:italic>HH</jats:italic> invariant mass are obtained. Resonant production limits are set for scalar and spin-2 graviton hypotheses in the mass range 500 to 3000 GeV. </jats:p>
