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{sup -1} collected with the D0 detector at the Fermilab Tevatron Collider in pp collisions at {radical}(s)=1.96 TeV. In the channel LQLQ{yields}eq{nu}{sub e}q{sup '}, where q, q{sup '} 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 LQ mass, assuming equal probabilities of LQ decays to eq and {nu}{sub e}q{sup '}.
