Title: Search for first generation leptoquark pair production in the electron + missing energy + jets final state

Abstract

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 pp collisions at √s = 1.96 TeV. In the channel LQLQ → eqν eq, 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 ν eq.
