We present a search for the pair production of first generation scalar leptoquarks (LQ) in data corresponding to an integrated luminosity of 5.4 fb−1 collected with the D0 detector at the Fermilab Tevatron Collider in ppbar collisions at s√=1.96 TeV. In the channel LQLQˉ→eνeqq′, where q, q' are u or d quarks, no significant excess of data over background is observed, and we set a 95% C.L. lower limit of 326 GeV on the leptoquark mass, assuming equal probabilities of leptoquark decays to eq and νeq′.
